When the third user sends a connection request, you will be prompted to disconnect the original connection. This new feature is currently only available in Windows 2003.

Seven, let IE install objects with invalid signatures.

SP2 In order to improve security, it is stipulated that if an object contains an invalid signature, Internet Explorer will prohibit its installation by default. By default, even administrators cannot download and install this invalid signature object through Internet Explorer.

After installing SP2, if you really need IE to download and install such invalid signature objects when browsing the page, you can adopt the following methods: In IE, click Tools/Internet Options, and then click Open Advanced Tab; Select the option "Allow running or installing software even if the signature is invalid"; Finally confirm the exit.

After Windows XP SP2 is started, sometimes a shield icon is displayed in the tray area of the taskbar, sometimes it is not displayed, and sometimes the icon is displayed as green, red or yellow.

If SP2 Security Center is working properly, it will not display icons in the tray area of the taskbar. If the Security Center works normally, manually open the Security Center, and a green icon will appear in the tray area of the taskbar, indicating that the system is safer.

If the red icon appears, it means that the firewall or automatic update is not enabled in the current system, or the antivirus software is not updated, or the virus definition library has expired. If the yellow icon appears, it will warn the system of potential danger. You should open the security center in time, adjust the security settings and enhance the security of the system.

The Security Center (WSC) reported an unknown status, which means that WSC cannot determine whether the virus signature library file of virus monitoring software has been updated recently or whether the local library file has been updated. Because anti-virus software can only find and remove the latest virus after updating the latest virus signature library, the security center should warn users.

Therefore, you should contact the manufacturer of antivirus software to confirm whether there is an upgrade package for the software, so that SP2 can detect its virus signature update online. If there is an upgrade package, buy anti-virus software and update the virus signature library; Otherwise, the security center is configured and the user manually monitors its status.

X.SP2 can display the verification codes of some websites.

Some websites (such as China Merchants Bank website) need to enter a verification code when registering or logging in. The image format of most verification codes is. Xbm。 Many Unix host websites use images in Xbm format when designing verification codes. However, after installing SP2, the verification code of the login page cannot be displayed, which makes you unable to log in or register. The reason for this phenomenon is that SP2 removes the support for the image/x-xbit bitmap image format by default, so IE cannot display the verification code image in Xbm format.

To solve this problem, you can click Start/Run, enter Regedit.exe Enter in the input box, open the Registry Editor, then locate HKEY _ Local _ Machine Software Internet Explorer Security in the tree on the left, create a new DWORD key named "BlockXMB" in the panel on the right, set the key value to "0", and finally restart IE to solve the problem.
