In-depth study of remote control in XP system

1. Windows XP Remote Assistance Application

"Remote Assistance" is a simple remote control method provided with Windows XP. The initiator of the remote assistance sends a request for assistance to the contact in the Messenger through MSN Messenger. After obtaining the consent of the other party, the remote assistance can be performed. The computer of the assisted party in the remote assistance will be temporarily assisted (in the remote assistance program) Known as the expert's control, the expert can perform system maintenance, install software, handle certain problems in the computer, or demonstrate certain operations to the assisted person in the controlled computer.

If you have already installed MSN Messenger 6.1, you will need to install Windows Messenger 4.7 to be able to perform Remote Assistance.

When using Remote Assistance, click the "Operation → Seek Remote Assistance" menu command in the main dialog of MSN Messenger. Then select the contact you want to invite in the Seek Remote Assistance dialog that appears. When the invitation is accepted, the Remote Assistance program dialog box opens, as shown in Figure 1. The invitee can manipulate the inviter's computer by clicking the Take Over Control button in the Remote Assistance dialog.

master both sides can also type a message in the "Remote Assistance" dialog box, chat, and send files as you would in MSN Messenger. If the accused wants to terminate the control, you can retrieve control of the computer by pressing the Esc key or by clicking the "Terminate Control" button.

2. Windows XP "Remote Desktop" application

Remote control using "Remote Assistance" is very simple to implement, but it must be coordinated by the master and the master, so Windows XP Professional provides another Remote control mode - "Remote Desktop", with "Remote Desktop", you can remotely control the computer through the network away from the office. Even if the host is in an unattended situation, "Remote Desktop" can still be carried out smoothly. Users can use the data, applications, and network resources on the computer in this way. It also allows your colleagues to access the desktop of your computer for easy collaboration.
(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 host's Internet connection can be a normal dialing method, because Remote Desktop can perform remote control by transmitting only a small amount of data (such as display data and keyboard data).

To start the Remote Desktop feature of Windows XP, you must log in to the system as an administrator or a member of the Administrators group, so that you have the Windows XP Remote Desktop permission.

Right click on the "My Computer" icon and select the "Properties" command. In the dialog that appears, click the Remote tab and click to select the Allow users to connect to this computer remotely option box. Click the Select Remote User button and then click the Add button in the Remote Desktop User dialog box. The Select User dialog box appears.

Click the Location button to specify the search location, and click the Object Type button to specify the type of object to search for. Next, in the Enter the object name to select box, type the name of the object you want to search for and click the Check Name button. After you find the user name, click the OK button to return to the Remote Desktop User dialog. In the box, the found user will appear in the list of users in the dialog box.

If no users are available, they can be created using User Accounts in the Control Panel. All users listed in the Remote Desktop Users list can use Remote Desktop to connect to this computer if It is the management group member who has the permission to connect even if it is not listed here.

(2) Client software installation

Windows XP users can use the "Remote Desktop Connection" program that comes with the system (in "Start → All Programs → Accessories → Communication" "Medium" to connect to the remote desktop. If the customer's operating system is Windows 9X/2000, install the Remote Desktop Connection client software from the Windows XP installation CD.

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

(3) Access Remote Desktop

Run the "Remote Desktop Connection" program on the client, the "Remote Desktop Connection" dialog box will be displayed, click the "Options" button to expand the dialog box. All options, as shown in Figure 2, type the IP address or domain name, user name, password of the remote host in the "General" tab, and then click the "Connect" button. After the connection is successful, the "Remote Desktop" window will open. You can see the desktop settings, files, and programs on the remote computer, and the computer stays locked. If you don't have a password, no one can use it or see what you are doing with it.

If you log off and end the Remote Desktop, Remote Desktop can connect window, click the "Start" button, then press the conventional way to log off the user logs off.

(4) Remote Desktop Web Connection

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

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

Since "Remote Desktop Web Connection" is an optional WWW service component in Internet Information Services (IIS), in order for Windows XP host to provide "Remote Desktop Web Connection" functionality, this component must be installed 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 to select it in the Windows Component Wizard dialog box. "Internet Information Services" option and click the "Details" button, select the "World Wide Web Service → Remote Desktop Web Connection" option, then return to the "Windows Components Wizard" dialog box after confirming, click the "Next" button to start installation.

Next, run the "Internet Information Services" program in the "Administrative Tools", expand the folder hierarchy, find the "tsweb" folder, right-click, and select the "Properties" command.

Click the "Directory Security" tab in the "Properties" dialog box that appears, click the "Edit" button in the "Anonymous Access and Authentication Control" column, and the "Authentication Method" appears. The "Anonymous access" option is selected in the dialog box. This way we can use IE to access "Remote Desktop".

Run IE on the client and type the server address in the address bar by pressing "http://server address (domain name)/tsweb". If the server address is 218.76.1199.5, you can enter the address bar. Enter http://218.76.219.5/tsweb/", press Enter, the "Remote Desktop Web Connection" page will appear in the IE window, as shown in Figure 3, type in the "Server" field in the web page the name of the remote computer you want to connect, click the "connect" button connected to the remote desktop.

addition to remote Desktop and remote assistance, Windows XP also provides a program sharing, in a sense, It is also a kind of remote control of the program, and NetMeeting also has program sharing function.

The above remote control methods must be carried out in Windows XP or Windows Server 2003, and the function is relatively simple. Remote control in other operating systems, or the need for remote control to provide more powerful features, requires the use of other third-party remote control software.
