(1) Configure Remote Desktop Host

The remote desktop host must be a computer with Windows XP installed. The host must be connected to the Internet and have a valid public IP address. The Internet connection mode of the host can be a normal dialing method, because "Remote Desktop" can transmit remote control only by transmitting a small amount of data (such as display data and keyboard data).

To start the Remote Desktop feature of Windows XP, you must be logged in to the system as an administrator or a member of the Administrators group, so that you have the option to start Windows XP & ldquo; Remote Desktop.

(2) Client software installation

Windows XP users can use the system's own "remote desktop connection" program (in “ start → all programs → attachments → communication & rdquo; in) to connect to the remote desktop. If the customer's operating system is Windows 9X/2000, you can install the "Remote Desktop Connection" client software on the Windows XP installation CD.

Insert the Windows XP CD-ROM into the client's CD-ROM drive. On the Display “Welcome" page, click the “Execute Other Tasks” option, and then select “Set Remote” from the page that appears. The Desktop Connection & rdquo; option, then follow the prompts to install.

Remote Desktop also provides a Web connection function, referred to as “Remote Desktop Web Connection”, so that the client does not need to install a dedicated client. The software can also use the “Remote Desktop” function, which is less demanding on the client and more flexible to use. Any computer running IE can use the “Remote Desktop” function.

Let's first take a look at the configuration of the server.

Because the "Remote Desktop Web Connection" is an optional WWW service component in Internet Information Services (IIS), it is necessary for the Windows XP host to provide the "Remote Desktop Web Connection" function. Install the component first. To do this, run the “Add or Remove Programs” item in the “Control Panel” and then click the “Add/Remove Windows Components” option in the “Add or Remove Programs” dialog box, at “ ; in the Windows Components Wizard & rdquo; dialog box, select the "Internet Information Services" option and click the "Details" button, select the "World Wide Web Service & Rarr; Remote Desktop Web Connection" option, and then return to "ld" ; Windows Component Wizard & rdquo; dialog box, click the "Next" button to start the installation.

Next, run the “Internet Information Service” program in the “Administrative Tools”, expand the folder hierarchy, find the “tsweb” folder, right click and select “ldquo; Attribute & rdquo; command.

Click the "Directory Security" tab in the "Properties" dialog box that appears, and click the "Edit" button in the "Anonymous Access and Authentication Control" In the “Authentication Method” dialog box that appears, select the “Anonymous Access” option. This way we can use IE to access & ldquo; Remote Desktop & rdquo;

Run IE on the client, type the server address in the address bar in the format of "http://server address (domain name) /tsweb", if the server address is 218.76.1199.5, then the address can be Enter "“http://218.76.219.5/tsweb/” in the field, after the carriage return, the page of "Remote Desktop Web Connection" will appear in the IE window, as shown in Figure 3, in the web page. In the Server & rdquo; column, type the name of the remote computer you want to connect to and click the “Connect” button to connect to the remote desktop.

In addition to remote desktop and remote assistance, Windows XP also provides program sharing. In a sense, it is also a remote control of the program, and NetMeeting also has program sharing.

The above remote control methods must be performed in Windows XP or Windows Server 2003, and the functions are relatively simple. To perform remote control in other operating systems, or to require remote control to provide more powerful features, you need to use other third-party remote control software.
