network brings convenience to the application, but also brings danger, therefore, management and security become a very serious problem. As a replacement for Windows 9x/Me and Windows 2000, Windows XP has reached an unprecedented level of support for the network. You may not have fully discovered these useful features when you are busy. Let us show you one by one. There is always something for you! 1. Install the wireless network When you insert a wireless network adapter into your computer, XP will automatically pop up a “Connect to Wireless Network” dialog box.

The SP2 system has an alarm when accessing the network. Some users who have just installed SP2 ask why the "Windows Security Alert" prompt box pops up when FTP, QQ chat, QQ game, MSN Messenger login. What are the security risks of these programs? In fact, this is a problem caused by the Windows Firewall feature added by SP2. Its use is somewhat similar to the famous "Skynet Firewall", we have to manually set the network access status of the application. When the Windows Firewall is in the "Enable (recommended) no exception" state, all packets will be blocked. This function can better solve the troubles caused by network attacks and malicious programs. Workaround: When using the application, click the "Unblock" button in the pop-up "Windows Security Alert" dialog box. 3, XP routing desktop vulnerability solution Windows XP provides remote desktop function, which has been confirmed to have design flaws, which may cause the attacker to obtain the account information of the system remote desktop, which will help him to further attack. When the connection is established, use Windows XP Remote Desktop to send the account name in clear text to the client connecting to it. The account name sent is not necessarily the user account of the remote host, but the account name most commonly used by the client. The sniffing program on the network may capture these account information. Solution: Go to the Microsoft homepage to download the corresponding patch and temporarily stop using the remote desktop by right-clicking "My Computer", selecting "Properties", in the pop-up window, select the "Remote" tab, check Drop the hook before the "Allow users to connect to this computer remotely" checkbox and click "OK". 4. The image in the Html file cannot be displayed when the SP2 system accesses the network Some users report that after installing SP2, sometimes when the Html file is opened in IE, an ActiveX error message will appear and the picture cannot be displayed normally. This problem may be caused by the enhanced security features in SP2. By default, SP2 enables security policies that help users' computers defend against malicious attacks. Solution: Open the Registry Editor and go to the "HKEY_LOCAL_MacHINE\\Software\\Micro soft\\Internet Explorer\\Main\\FeatureControl \\FEATURE_LOCALMacHINE_LOCKDOWN" branch. The values of the "IExplore.exe" and "explorer.exe" keys on the right side of the window will be displayed.

If you are browsing a Win 9x machine, for example, typing "\\computername" in the neighborhood's address bar, XP's machine will check the "task plan" on the machine it is connecting to. This search process can cause up to 30 seconds of delay.
