Outlook Client Configuration







Home Networking Diagram

1. Wireless Router Network Diagram
Common layout for WiFi-based home networks
This diagram illustrates use of a Wi-Fi wireless network router as the central device of a home network. See below for a detailed description of this layout.


Key Considerations -

All devices connecting to a wireless router must possess a working network adapter. As illustrated in the diagram, connecting to the router a broadband modem (that has one or more built-in adapters) enables sharing of a high-speed Internet connection.

Wireless routers technically allow dozens of computers to connect over WiFi links. Nearly any residential wireless router will have no trouble supporting the number of wireless devices found in typical homes. However, if all WiFi computers attempt to use the network at the same time, slowdowns in performance should be expected.

Many (but not all) wireless network routers also allow up to four wired devices to be connected via Ethernet cable. When first installing this kind of home network, one computer should be cabled to the wireless router temporarily to allow initial configuration of the wireless features. Employing Ethernet connections after that is optional. Using permanent Ethernet connections make sense when the computer, printer or other device lacks WiFi capability or cannot receive an adequate wireless radio signal from the router.

Optional Components - Networking the router for Internet access, printers, game consoles and other entertainment devices is not required for the rest of the home network to function. Simply omit any of these components shown that do not exist in your layout.

Limitations - The WiFi portion of the network will function only to the limit of the wireless router's range. The range of WiFi equipment varies depending on many factors including layout of the home and any radio interference that may be present.

If the wireless router does not support enough Ethernet connections for you needs, add a secondary device like a network switch to expand the wired portion of the layout.


2. Ethernet Router Network Diagram
Common layout for Ethernet-based home networks
This diagram illustrates use of a wired network router as the central device of a home network. See below for a detailed description of this layout.


Key Considerations - Many (but not all) wired network routers allow up to four devices to be connected via Ethernet cable.

All devices connecting to an Ethernet router must possess a working Ethernet network adapter.

Optional Components - Networking the router for Internet access, printers, game consoles and other entertainment devices is not required for the rest of the home network to function. Simply omit any of these components shown that do not exist in your layout.

Limitations - If the Ethernet router does not support enough Ethernet connections, add a secondary device like a network switch to expand the layout.


3. Hybrid Ethernet Router / Wireless Access Point Network Diagram

Common layout for hybrid home networks
This diagram illustrates use of a hybrid wired network router / wireless access point home network. See below for a detailed description of this layout.


Key Considerations - Most (but not all) wired network routers allow up to four devices to be connected via Ethernet cable. A wireless access point consumes one of these available ports, but it then enables many (dozens of) WiFi devices to join the network.

Nearly any home network wireless access point will have no issue managing to support the number of wireless devices there. However, if all WiFi computers attempt to use the network at the same time, performance slowdowns can result.

All devices connecting to an Ethernet router must possess a working Ethernet network adapter. All devices connecting a wireless access point must possess a working WiFi network adapter.

Optional Components - Networking of Internet access, printers, game consoles and other entertainment devices is not required for either the router or access point to function. Simply omit any of these components shown that do not exist in your layout.

You can choose which devices to connect to the router and which to the wireless access point. Additional network adapters may be needed to convert some Ethernet devices, particularly printers and game consoles, to work wirelessly.

Limitations - The WiFi portion of the network will function only to the limit of the wireless access point's range. The range of WiFi equipment varies depending on many factors including layout of the home and any radio interference that may be present.

If the wireless router does not support enough Ethernet connections, add a secondary device like a network switch to expand the wired portion of the layout.


4.Direct Connection Network Diagram

Common layout for simple Ethernet home networks
This diagram illustrates direct connection without a router or other central device on the home network. See below for a detailed description of this layout.


Key Considerations - Direct connection can be achieved with several different types of cabling. Ethernet cabling is the most common, but even simpler (slower) alternatives exist including RS-232 serial cable, and parallel cable.

Direct Connection is common for game consoles to support two-player network gaming (e.g., Xbox System Link).

Optional Components - Connecting to the Internet requires that one computer possess two network adapters - one to support the Internet connection and one to support the second computer. Additionally, Internet connection sharing software must be installed to allow the second computer Internet access. If Internet connectivity is not necessary, these things can be omitted from this layout.

Limitations - Direct connection works only for a single pair of computers / devices. Additional devices cannot join such a network, although other pairs can be connected separately as shown above.

5. Ad Hoc Wireless Network Diagram

Common layout for WiFi-based home networks
This diagram illustrates use of a so-called ad hoc wireless setup in a home network. See below for a detailed description of this layout.


Key Considerations - Using ad hoc Wi-Fi mode eliminates the need for a network router or access point in a wireless home network. With ad hoc wireless, you can network computers together as needed without needing to be in reach of one central location. Most people use ad hoc Wi-Fi only in temporary situations to avoid potential security issues.

Optional Components - Networking an ad hoc layout for Internet access, printers, or game consoles and other entertainment devices is not required for the rest of the home network to function. Simply omit any of these components shown that do not exist in your layout.

Limitations - All devices connecting via ad hoc wireless must possess a working Wi-Fi network adapter. These adapters must be configured for "ad hoc" mode instead of the more typical "infrastructure" mode.

Because of their more flexible design, ad hoc Wi-Fi networks are also more difficult to keep secure than those using central wireless routers / access points.

Ad hoc Wi-Fi networks support a maximum of 11 Mbps bandwidth, while other Wi-Fi networks may support 54 Mbps or higher.


6. Ethernet Hub/Switch Network Diagram

Common layout for Ethernet-based home networks
This diagram illustrates use of an Ethernet hub or switch on a home network. See below for a detailed description of this layout.


Key Considerations - Ethernet hubs and switches allow multiple wired computers to network with each other. Most (but not all) Ethernet hubs and switches support up to four connections.

Optional Components - Networking of Internet access, printers, or game consoles and other entertainment devices is not required for the rest of this home network layout to function. Simply omit any of these components shown that do not exist in your design.

Additional hubs and switches can be incorporated to the basic layout shown. Connecting hubs and/or switches to each other expands the total number of computers the network can support up to several dozen.

Limitations - All computers connecting to a hub or switch must possess a working Ethernet network adapter.

As shown, unlike a network router, Ethernet hubs and switches cannot interface directly to an Internet connection. Instead, one computer must be designated as controlling the Internet connection and all other computers access the Internet through it. Internet connection sharing software can be installed on each computer for this purpose.


7. Phoneline Home Network Diagram
Layout for HPNA-based phoneline home networks
This diagram illustrates use of Home Phoneline Networking Alliance equipment to build a home network. See below for a detailed description of this layout.


Key Considerations - Phoneline networks utilize the ordinary telephone wiring of a residence to carry home network communications. As with Ethernet or Wi-Fi networks, phoneline networks require each device to have a compatible phoneline network adapter installed. These adapters are connected by ordinary phone wires (or sometimes CAT5 Ethernet cable) to telephone wall outlets.

When connecting multiple computers with phoneline networking, one central computer "gateway" must be established. The gateway represents the network's primary device for connecting to the Internet. A few models of home network routers (sometimes called "residential gateways") support phoneline networking today. Otherwise, you must designate one computer as the gateway and install two network adapters on this computer to enable it for gateway functions. Depending on the type of primary device chosen, hybrid networks with a combination of phoneline, Ethernet or Wi-Fi devices can be created.

The Home Phoneline Networking Alliance (HomePNA) develops technology standards that compatible phoneline equipment must support.

Optional Components - As mentioned above, a network router is optional when building a phoneline home network. Phoneline networking also works regardless of whether the residence is subscribed either to basic local telephone service or to DSL Internet service.

Limitations - HomePNA phoneline networking has proven much less popular than Wi-Fi or Ethernet alternatives. Phoneline networking products will generally be more difficult to find, and there will be fewer choices of models for this reason.

All phoneline network equipment must be connected to the same electrical circuit within the residence. Specifically, residences that have two phone lines installed, must choose one or the other line to connect all devices.

The range of an HomePNA (version 2.0) phoneline network is about 1000 feet (300 m). The maximum bandwidth of an HomePNA 2.0 network is 10 Mbps, while an HomePNA 3.0 network supports more than 100 Mbps. The speed of phoneline networking can suffer depending on the quality of phone cables installed in the residence.

8. Powerline Home Network Diagram

Layout for HomePlug powerline home networks
This diagram illustrates use of HomePlug equipment to build a powerline home network. See below for a detailed description of this layout.


Key Considerations - Powerline networks utilize the ordinary electrical circuity of a residence to carry home network communications. Available powerline equipment includes network routers, network bridges and other adapters.

To connect to a powerline network, one end of the adapter plugs into a standard electric wall outlet while the other connects to a device's network port (usually Ethernet or USB). All connected devices share the same communication circuit.

The HomePlug Powerline Alliance develops technology standards supported by compatible powerline equipment.

Optional Components - Not all devices on the home network must be connected to a powerline router; hybrid networks with Ethernet or Wi-Fi devices can be joined with the powerline network. For example, a Wi-Fi powerline bridge can optionally be plugged into a wall outlet, enabling wireless devices to connect to it and in turn to the rest of the powerline network.

Limitations - HomePlug phoneline networking remains much less popular than Wi-Fi or Ethernet alternatives. Powerline networking products will generally be more difficult to find with fewer choices of models for this reason.

Powerline networks generally do not work as reliably if devices plug into power strips or extensions cords. Connect directly to the wall outlets for best results. In homes with multiple circuits installed, all devices must connect to the same one circuit to communicate with each other.

The maximum bandwidth of a HomePlug (version 1.0) powerline network is 14 Mbps, while the newer HomePlug AV standard supports more than 100 Mbps. Poor quality electrical wiring as found in older homes can degrade the performance of a powerline network.

Step-by-Step Guide: How to set up a VPN

HOW TO SET UP A VPN


Step 1: Setup requirements

There are hardware- and software-based VPN solutions. In this step-by-step guide, I will be explaining a software approach to creating a VPN using Microsoft products.

To create a VPN, you will need three separate Windows 2003 servers and at least one remote client. The remote client's machine needs to be running Windows XP.

The first Windows 2003 server your VPN will need is basically an infrastructure server. It must act as a domain controller, DHCP server, DNS server and certificate authority. If you already have a Windows 2003 network in place, you don't need to go out and buy a server to fit this role.

Any Windows 2003 domain will already have at least one domain controller and one server acting as a DNS server. Most Windows 2003 networks are also running DHCP services. If you already have all these services in place, the only thing you will have to worry about is setting up a certificate authority (which I show you how to do in Step 3). For now, you just need to know that the server acting as a certificate authority must be running Windows Server 2003 Enterprise Edition.

The second server you will need is a VPN server. Windows Server 2003 Standard Edition and Enterprise Edition both ship with the necessary software. Therefore, you won't need any special software on this server. The only specific hardware this server needs is two NICs. One NIC will connect to the Internet and the other will connect to your private corporate network.

The final server you will need is an authentication server. When remote users attempt to access your corporate network through a VPN, they need to be authenticated. The mechanism of choice for authenticating remote users is a RADIUS server. RADIUS is an acronym standing for Remote Authentication Dial In User Service. Microsoft includes its own version of RADIUS in Windows Server 2003 Standard Edition and Enterprise Edition. The Microsoft version of RADIUS is called Internet Authentication Service (IAS). There are no special hardware or software requirements for this server.

The last thing that I want to talk about as part of this step in the tutorial is server placement. Each of the servers I have discussed will be connected to your private network via a hub or switch. The only server that will have any external connectivity is your VPN server. It is a security risk to connect the VPN server directly to the Internet though. It is best to place a firewall in front of the VPN server so you can filter out everything but VPN traffic.

In Step 2, we'll begin the domain configuration process. Your network should contain the required Windows Server 2003 domain controller and DNS server before moving on to the next step.

Step 2: Implement DHCP services
  1. Open the server's Control Panel and select Add or Remove Programs.

  2. When the Add or Remove Programs dialog box appears, click the Add/Remove Windows Components button.

  3. Select the Networking Services option and then click Details.

  4. Now select Dynamic Host Configuration Protocol (DHCP) from the list of network services, then click OK, followed by Next.

    Windows will now install the DHCP services. When the installation completes, you will have to create an address scope and authorize the DHCP server to function on your network.

  5. To do so, select the DHCP option from the Administrative Tools menu to open the DHCP console.

  6. Right click on your server within the DHCP console and select Authorize.

  7. After you authorize the DHCP server, right click on the server's listing within the console again and select New Scope. This will launch the New Scope Wizard.

  8. Click Next to bypass the wizard's welcome screen.

  9. Enter a name for the scope that you are creating then click Next. (You can call it anything you want, but for the purposes of this tutorial, I will be referring to the scope as 'Corporate Network.')

  10. You will now be asked to enter an IP address range. Just specify a start and end address that is consistent with the IP addressing scheme you are already using, but that does not overlap any existing addresses. The Length and Subnet Mask fields will be filled in for you automatically.

  11. The next three screens contain settings that you don't have to worry about. Just click Next three times until you reach the Router (Default Gateway) screen.

  12. Enter the IP address of your network's default gateway, click Add, then Next.

  13. Type in the name of your domain and the IP address of your DHCP server and click Next.

  14. Click Next again to skip the WINS configuration screen.

  15. Finally, verify that the Yes, I Want To Activate The Scope Now option is selected then click Next and Finish.

Step 3: Create an enterprise certificate authority

Before I show you how to create an enterprise certificate authority, I want to give you a few words of caution. Installing a certificate authority is not a process to be taken lightly. If someone gains unauthorized access to your certificate authority, that person pretty much owns your network. Likewise, if a certificate authority server crashes, it can be devastating to your network.

Therefore, protect your certificate authority server the way you would protect a nuclear bomb. Make sure that it is as secure as possible and that you perform full system backups frequently. You also want to protect those backups so they are not accidentally compromised.

  1. With that said, select Add/Remove Programs from the Control Panel and click the Add/Remove Windows Components button.

  2. Choose Certificate Services from the list of Windows components.

  3. You will see a warning message indicating that you won't be able to rename the machine or change its group membership after the certificate services are installed. Click Yes to acknowledge the warning and then click Next to begin installing the certificate authority.

  4. Choose Enterprise Root CA as the type of certificate authority you want to install and click Next.

    You will now be prompted to enter a common name for the certificate authority. You must also select a certificate validity period. The default setting allows certificates to be valid for five years, but you can increase or decrease this time frame according to your own corporate security policy.

  5. Fill out these two items, then click Next. Windows will begin generating cryptographic keys.

  6. You will be prompted to enter a location for the certificate database. Select the default location (unless you want to place the databases onto a volume with better performance or fault tolerance) and click Next.

  7. You will now see a message indicating that Windows must restart the IIS services. Click 'Yes' and Windows will install the necessary components.

Step 4: Install IAS

IAS is the Windows Server 2003 implementation of RADIUS. The IAS server will authenticate users who enter your corporate network through the VPN connection. As such, your IAS server must be a member server in one of your domains and must be running Windows Server 2003.
  1. To install IAS, open the Control Panel and choose the Add/Remove Programs option.

  2. When the Add or Remove Programs dialog box appears, click Add/Remove Windows Components.

  3. Select the Networking Services option and click Details.

  4. Now, choose the Internet Authentication Service option.

  5. Click OK, followed by Next, to install IAS.

Step 5: Configure IAS
  1. Go to Administrative Tools -> Internet Authentication Service.

  2. From here, the first thing you need to do is to register your IAS server with Active Directory. To do so, right click on the Internet Authentication Service (Local) container and select Register Server in Active Directory.

  3. Click OK to complete the registration process.

  4. Now, right click on the RADIUS Clients container and select New RADIUS Clients. If you happen to know the IP address or DNS name of one of your client machines, go ahead and enter it along with a friendly name. Otherwise, leave it for now, as we'll be filling it in later when we set up the client connections anyway.

  5. Click Next.

  6. You will now be prompted for a shared secret. A shared secret is an encryption key used by the RADIUS Server and the client. Make sure that the Client Vendor option is set to RADIUS Standard, enter a shared secret, and click Finish.

Step 6: Create a remote access policy
  1. ight click on the Remote Access Policies container and select the New Remote Access Policy option. This will open the New Remote Access Policy Wizard.

  2. Click Next to bypass the wizard's Welcome screen.

  3. Verify that the Typical Policy for a Common Scenario option is selected and then enter 'VPN Access' as the policy name and click Next.

  4. Select the VPN option and click Next again.

  5. This screen gives you the opportunity to apply the policy to either users or groups. If you haven't already done so, I recommend taking a time out to create an Active Directory group based on users who will access the network through the VPN. You can then assign this group to the policy that you are creating.

  6. Click Next and you will see the Authentication Methods screen.

  7. Verify that MS CHAPV2 is selected and click Next.

  8. Confirm that only the Strongest Encryption option is selected and click Next, followed by Finish.

Step 7: Configure the VPN server
  1. Begin by opening the server's Network Connections folder and renaming the connections to something more meaningful. For example, you might name the connections to Corporate and Internet, or something like that.

  2. Go to Administrative Tools -> Routing and Remote Access to open the Routing and Remote Access console.

  3. Right click on your VPN server in the console tree and select Configure and Enable Routing and Remote Access. This will launch the Routing and Remote Access Server Setup Wizard.

  4. Click Next to bypass the wizard's welcome screen. You will then see the wizard's configuration screen.

  5. Select Remote Access (Dial-Up or VPN) and click Next.

  6. Mark the VPN checkbox and click Next.

  7. You will now see a screen that displays your machine's network connections. Select the connection attached to the Internet, verify that the Enable Security checkbox is selected and click Next.

  8. Verify that Automatically is selected and click Next.

  9. Now choose the option to set the server up to work with a RADIUS Server and click Next.

  10. Enter the IP address of your RADIUS server and the shared secret that you assigned to the RADIUS Server.

  11. Click Next, then Finish.

Step 8: Associate the VPN server with the DHCP server

  1. Navigate through the console tree to your server -> IP Routing -> DHCP Relay Agent.

  2. Right click on the DHCP Relay Agent container and select Properties.

  3. Enter the IP address of your DHCP server and click Add, followed by OK.

Your VPN server is now configured. You're in the home stretch! All you need to do now is configure your clients to work with the VPN you have created.


Step 9: Configure your remote clients

You may recall that we had to create a special security group for any user who is going to be accessing the network over the VPN connection. Therefore, I am assuming your remote users have been added to the necessary group and your client computers already have Internet access.

To allow a Windows XP client computer to access your private network, you must tell it to use a VPN connection.

  1. To do so, open the Control Panel and select the Network and Internet Connections option.

  2. Select the Create A Connection to the Network At Your Workplace option.

  3. Windows will now ask you if you want to create a dial-up connection or a VPN connection. Select the VPN option and click Next.

  4. At this point, you will see the Company Name prompt. Here you can enter the name of your company, the name of the server that you are connecting to, or anything else to describe the connection.

  5. Click Next. You will be prompted to enter the IP address of the server that you are connecting to. This will be the external IP address (the one connected to the Internet) of your VPN server.

  6. Click Next again, followed by Finish to create your connection.

Step 10: Test the client connection
  1. Double click on the connection in the list of available connections.

  2. You will be prompted for a username and password. Rather than entering your logon credentials, click the Properties button.

  3. In Properties, select the Networking tab.

  4. Set Type of VPN to PPTP VPN and click OK.

  5. You will be returned to the VPN logon screen. Enter your username in the domain/username format.

  6. Now enter your password and click Connect.

  7. There is a chance that you may be prompted as to which connection you want to use. If prompted, select the LAN Connection option.

  8. Once you are connected, go to Start -> Run and enter the \\servername\ROOT command.

You should see the content's of your server's C drive (assuming that you have the rights). Of course, it's rare that you would be directly accessing the server's C drive. More often, you would be accessing a specific share on the server. To do so, you would enter \\servername\sharename.


Step 11: Alternate VPN configuration options

In this step-by-step guide, I have outlined only one of maybe half a dozen different types of client VPN connections. There are many variations that involve different encryption or authentication techniques. You can read about these alternate client configurations here.

Connect to an XP machine using Remote Desktop

With Remote Desktop, you can connect to your Windows XP machine from anywhere on your Local Area Network (LAN). You can even set it up so that you can connect to the machine over the Internet from anywhere in the world.

Prior to Windows XP, if you wanted this kind functionality, you had to do some special configuring using Windows Terminal Services.

In this blog, I will show you how to configure the Remote Desktop Web Connection and use Internet Explorer as a remote client to connect to your XP machine.

Installing the Remote Desktop Web Connection

To connect to your machine from a remote location, you must install the Remote Desktop Web Connection on the Windows XP system you want to access remotely. This feature is basically a component of XP’s Internet Information Services (IIS).To install the necessary files for the Remote Desktop Web Connection, you will need to have access to your Windows XP CD. To Install IIS and the Remote Desktop Web Connection, follow these steps:

  1. From the Control Panel, click the Add/Remove Programs applet.
  2. Click Add/Remove Windows Components.
  3. Select Internet Information Services and click Details.
  4. Select World Wide Web Services from the Subcomponents of Internet Information Services and click Details.
  5. Select the Remote Desktop Web Connection check box and click OK.
  6. Click OK, then click Next to install and configure IIS and the Remote Desktop Web Connection.
  7. Click Finish when complete.

Configuring Remote Desktop

By default, the Remote Web Connection files are installed to the \\%systemroot%\Web\Tsweb directory of your Web server. Let’s verify that the files were installed correctly and make sure that anonymous access is selected:

  1. Open Start | Programs | Administrative Tools | Internet Information Services.
  2. Expand Local Computer | Web Sites | Default Web Site and select Tsweb, as shown in Figure A.
  3. Right-click on Tsweb and click Properties.
  4. Click the Directory Security tab and choose Edit from Anonymous Access And Authentication Control.
  5. Check the Anonymous Access check box, as shown in Figure B, and then click OK twice.

Once you’ve properly configured the Remote Desktop Web Connection, it’s time to configure this computer to use Remote Desktop:

  1. Go to Control Panel | System Properties and select the Remote tab to display the options shown in Figure C.
  2. Select Allow Users To Connect
    Remotely To This Computer. You will see a dialog box reminding you to
    set up permissions and open up the appropriate ports on your firewall.
  3. Click the Select Remote Users button to open the dialog box shown in Figure D.
    Here, you can give the appropriate user(s) access to Remote Desktop.
    Click Add | Advanced | Find Now to display all of your users. Select
    your users and click OK.

Note:
All Administrators have access regardless of whether they are added to the list.

Connecting remotely

You’re now ready to connect to your computer from another Windows machine running Internet Explorer 4.0 or greater.

  1. Open IE from any Windows machine on the same network.
  2. Go to http://computer_name /tsweb (or http://ip_address /tsweb), and you’ll see the Remote Desktop Web Connection page, shown in Figure E.
  3. Type the computer name, choose your screen size/resolution, and click Connect.
  4. When
    you click the Connect button for the first time, you’ll be prompted to
    install the Microsoft Terminal Services Control. Click Yes and then
    enter your logon information, as we’ve done in Figure F.
  5. Click OK to log on to the remote computer. You should now see a screen similar to Figure G.

Note: Remember that to connect to your XP system by computer name from a remote location, you must be connected to your network via dial-up or VPN. If your Windows XP machine has a static IP address, you can connect to it over the Internet using the static IP as well. If you don’t have a static IP address, you can connect with port forwarding from the router or firewall in front of the XP machine, although connecting via dial-up or VPN is much easier and more secure.

If you are connecting to the Windows XP system from another XP system, you can simply go to Start | Programs | Accessories | Communications | Remote Desktop Connection and enter the
name or IP address of the machine you want to connect to, as shown in Figure H.

If you want to use the above method from a computer running Windows 95, 98, NT 4.0, or 2000, insert the Windows XP CD and wait until it loads. From the startup screen, click Perform
Additional Tasks and then click Set Up Remote Desktop Connection. Once installation is complete, you can access the Remote Desktop Connection client from Start | Programs | Accessories | Communications | Remote Desktop Connection. You can also download from the Internet.

You can now use either Internet Explorer or Windows XP’s Remote Desktop Connection client to connect to any remote system that is configured asa Remote Desktop host. With this functionality, you can connect to your computer from various locations to access your applications, files, contacts, etc. This feature provides solid functionality and good performance. It’s definitely worth taking a look at Windows XP if you think this feature can benefit employees who often need remote access to their systems from different locations.

Speed-up searching for network resources in Windows XP

Did you know that each time you open My Computer on Windows XP, your computer automatically searches for the network files and printers your specific login has access to? This entire process can decrease system performance to a crawl as well as take much longer to display all of your icons in the My Computer window. You have the ability to stop Windows from automatically searching for network resources and printers by performing the following:

  1. Open My Computer
  2. Select Tools | Folder Options
  3. Select the View tab and deselect Automatically Search for Network folders and Printers check box.
  4. Click OK.

Tip: Windows XP SendTo Hidden Gem

The SendTo feature in Windows XP is a hidden gem that I want to share with you. I don't think a day goes by that I do not take advantage of this feature.

Click Start Run and type sendto in the textbox.

The sendto folder opens up and allows you to enter shortcuts to folders that you find desirable. For example, you could enter a shortcut to your music, pictures, a network share, etc.

Once you have created your shortcuts, simply right-click on the documents of your choice and use the sendto feature to get them to the appropriate place.

Vista Tip: Open Command Window Here

I recently came across a tip while working within Windows Vista. Typically when I use the command prompt, I type cmd in the Run window and then browse to my appropriate directory.

In Windows Vista, you can avoid this extra time by browsing to the appropriate directory in Windows Explorer and then simply hold down the SHIFT key and right-click on the folder and choose Open Command Window Here.

35.创建浏览目录的快捷方式

  在桌面上创建一个快捷方式, 命令为:C:WINDOWSEXPLORER.EXE/n,/e,C:当你双击此快捷方式时,将会用“Windows资源管理器”浏览C:。当然,你可以用其他的目录名来替换命令中的C:

36.改变关机画面:

   记得以前可以改变开机画面吧,现在可以对关机画面动手喔!logow.sys 是等 待关机,logos.sys是最後丑丑的"您可以安全关机"_"都是 bmp 档,快动手 吧,原图是 320x400,256色!但是最後win95会把他放宽170%所以你可以先准 备一张 544x400 的图 再把这张图resize成320x400 再 rename 一下档名 就可以啦!(只能256色喔 )而且最好注意一下色盘的问题*开机画面也可以喔!logo.sys....

37.这个 .exe 用了哪些 .dll? 对应用程式右键单击,选 "快速检视"

38.厌倦图形介面了吗 想念以前先进入 dos 在打 win 进窗户吗在 msdos.sys中加入这一行BootGUI=0

39.在 win95的MS-DOS下使用长文件名

  只需要在文件名前后加引号("")即可。如:

  c:>dir "windows utilities"

  c:>cd "windows utilities"insteasy

  c:>edit "The list of my friends.txt"

40.加快软驱传输速度

  往软盘上存贮较多资料时,让人等得真有点烦。我们不可能对软驱的机械结构进行改造,但可以通过修改系统注册表以获得较高的数据传输速度,具体方法如下:

  打开系统注册表编辑器,找到

   “HEKY-LOCAL-MACHINESystemCurrentControlsetServicesClassFCD00",在其右边的窗口空白 处,占击鼠标的右健新建一个“DWORD”值,命名为“ Fore-Fifo”,健值设定为“0”。最后关闭注册表面化编辑器,重新启动电 脑,一切就OK了!

41.MSN背景修改:

  是不是觉得MSN的背景很单调呢?那么很简单,找到你喜欢的图片,估计好大小,最好是选择背景是透明的。命名为lvback.gif,找到目录CrogramFilesMessenger,将原来图片覆盖就OK了!

42.启动Winamp,并播放一首MP3

  2.然后按住[SHIFT]不放,再单击面板上的“停止”按钮

  3.你会发现音乐没有立即停止,而是逐渐降低音量直至完全消失,就象电台DJ 做的一样

43.1.启动QuickTime Movie Player,并打开一个mov文件

  2.当它播放的时候,点击暂停按钮,然后按下[Shift]键,并双击播映窗口

  3.电影开始倒放了,声音也是倒放的

44.在98下文件夹共享时,在共享名后面加个$可以把共享文件夹隐藏

45.Shift的另一个用法:

  ①大家经常使用Tab键、Spase键,但不知各位注意过没有,以上转换键都是顺向的,但你按住Shift不放,再用上述按键时,他的转换方向是不是倒过来了?

  ②在英文输入时,如果在小写状态下,按住Shift同时输入的字母为大写,反之 亦然;

46.智能ABC输入法中字母 “v”的用法:

  ①、在智能ABC输入中,V +数字(1~9),可以输入各种字符、图形、数字等,一试便知,奇妙无穷,但我想大多数人早都用了吧?

  ②、在智能ABC输入中,在输入拼音的过程中(“标准”或“双打”方式下),如果需要输入英文,可以不必切换到英文方式。键入“v”作为标志符,后面跟随要输入的英文,按空格键即可。

47.在以Word为代表的Office系列中,图形、文本框等非字符元素的位置的微调:以Word为例,在页面中插入图形或文本框等非字符元素,在页面排版时,经常为Word固有的所进所干扰,无法达到如意的效果。在使用中,笔者摸索出以下经验,与大家分享:

  ①、在调整某一图片(或其他元素,以下全以图片为代)的位置时,使用鼠标或方向键将其移动到大致位置时,按住Ctrl键,再用方向键移动,你会发现现在图片每次移动的间距比原来要小得多了,在Word要求的精度下应当完全达到您的要求了。

  ②、在调整某一图片(或其他元素,以下全以图片为代)的大小时,不使用鼠标时,图片变化的大小不连续,按住Alt键,再调节,现在其大小就可以任意调节了.

48. 大伙有没有碰过电脑黑屏一现象呀?按ESC以后,桌面上是否还留有许多黑色的影子呢?特别是下面的任务栏……不用鼠标找,就黑成一条了…………可以按“开始”――“关闭计算机”――“取消”,既可恢复.

49. 2000或者Xp下硬盘默认是共享的,即使你关闭共享,下次启动后还是会共享。

  想要让域内的工作站不盗窃你的个人工作成果,尝试一下建立一个批处理文件,并放在allusers的startup里(或者建一个快捷方式放在里面也可以)。内 容如下:net share c$/delete

  net share d$ /delete

  net share e$ /delete

50. 去除Windows 2000的默认共享

   修改注册表:对于各server版:在注册表编辑器(regedit.exe)中依次找到 “HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServiceslanmanservermeters”,之后 在其下新建一个“双字节值”,取名为“AutoShareServer”的,并将其值设为“0”。之后重新启动服务器即可。对于professional 版:同上面一样只是将AutoShareServer改为AutoShareWks

51.双击任务栏上的喇叭,如果觉得弹出音量控制面板占用桌面太打,或不能完全显示,按Ctrl+S后就会以mini方式显示,想恢复再按一次Ctrl+S就OK

52.有时会遇到引导型病毒或是光驱找不到的情况,一般在dos下执行fdisk /mbr 重启就可以解决

53.在windows目录下有一个sendto文件夹

  你可以把记事本的快捷方式放到里边去

  然后在希望用记事本打开的文件上右键发送到中选这个记事本即可

  也可以建立相应文件夹的快捷方式,比如music指向放音乐的文件夹

54.如何下载网页上的FLASH?

  1 用FLASHGET的资源探索就能下载网页上的FLASH

  2 到WINDOWS/Temporary Internet Files也能找到你要的FLSAH

  3 用缓存拾贝这个小软件也能拿你要的FLASH

55.解决COMS锁住问题

  在DOS命令行下打DEBUG

  -O 70 2F

  -O 71 2F

  -Q

56.有时候按默认路径安装一个软件,安装时由于没有在意,事后不知安装在哪,可以通过搜索(用当日时间),时间值最大的即为新装的文件,可以看出其所在的路径.

57.我们单位工作已经离不开电脑(各部门间电脑已连成网),大多数职工还不会使用电子信箱,领导要求用网络资源发放通知等。在这种情况下,笔者使用如下方法(简单,易行,不花分文)

  1.在任何一台电脑(作为邮件服务器)建立一个共享文件夹(只读),文件夹 命名为“XX”(信箱含义)。

  2.在其他电脑的桌面建立一个快捷键(做好影射网络资源,指向作为邮件服务 器的共享文件夹),快捷键命名为“公众信箱”

  3.将所有的“word”文件(通知),放在该文件夹内。

  4.用户只要点击该快捷键,便可看到所有的通知了.

58.ping x.x.x.x 太快!改称 ping x.x.x.x -t

59.在网吧上网被美萍锁住:在ie地址兰里输入"桌面"有50%机会打开我的电脑,利用一些东西比如文件->打开可以进行磁盘操作了.

60.用笔记本与投影仪搭配使用时有三种显示模式

  1.笔记本屏幕有显示、投影仪不显示;

  2.笔记本屏幕、投影仪均有显示;

  3.投影仪有显示、笔记本屏幕无显示.

  切换方法为按 Fn 键加F3(康柏的机子是这样的,也就是加上那个上面有个小 显示器图标的键啦)!
