FAQs about Win XP SP2

Since the launch of Windows XP SP2, many users can't wait to install it on their own systems, and want to fully feel the new experience SP2 brings to us. However, SP2 is not as expected. It brings new surprises and more doubts.

Windows XP SP2 has been released for a long time and has been installed by many friends. However, during use, we all encountered one or more problems. Here, I have summarized some common problems based on my experience and hope to help my friends!

　　Question 1:After successfully installing SP2, I always find that a red shield is displayed in the task bar during startup. After clicking enter, the system prompts "virus protection is not enabled". I installed the Norton Security Expert 2004! What's going on? But these two days have vanished mysteriously! Later, I thought that the built-in firewall of Norton would be better. I turned off the firewall of Windows in the option, but a red shield appeared in the taskbar. What should I do?

　　A:In SP2, Microsoft joined a "security center" console, which is mainly used to detect the status of virus protection, firewall, and automatic updates in the system. If it fails to be detected, a red shield will automatically pop up during the boot to show a warning. In fact, Windows SP2 cannot accurately detect most anti-virus software, even if you have installed it correctly! In fact, you only need to go to the "control panel", click "Suggestions" under "virus protection", and select "I have installed the anti-virus program and monitored its status ", you will not be reminded the next time you start the system. Currently, all major antivirus software vendors have improved their compatibility with SP2. You only need to upgrade to the latest version. Your "mysterious disappearance" is actually an automatic update of the software. In addition, you can refer to the above method for virus protection to solve the problem of the firewall. Of course, it is done in the "firewall" label. In addition, you can find the Security Center Service Security Center in the "Control Panel> Administrative Tools> Services" window and disable it.

　　Question 2:I am using ADSL virtual dial-up Internet access and no IP address is set. After SP2 is installed, the system automatically searches for the IP address each time the ADSL Modem is enabled. Naturally, each time it fails, a dialog box for IP address renewal appears. In addition, there is always a yellow exclamation mark on the local connection, indicating "restricted or not connected". Although dialing is not affected, it does not feel good. How can I disable this problem?

　　A:This problem occurs because the NIC does not have a fixed IP address. To ensure communication, Windows automatically assigns an IP address to the NIC.

Method 1: Go to the control panel and cancel the "notify me when this connection is restricted or there is no connection" option under the "Network Connection> Local Connection> Properties> General" tab.

Method 2: In the "Network Connection → local connection → properties → TCP/IP" attribute, specify an IP address for your NIC (note: make sure that the IP address of the ADSL Modem is in the same network segment ). We recommend that you use the second method, which can reduce the boot time at the same time!

　　Question 3:I use dual systems. After SP2 is installed, you can find the file boot. in the INI file, "multi (0) disk (0) rdisk (0) partition (2) "/NoExecute = OptIn" is added to Windows = "Microsoft Windows XP Professional"/fastdetect/NoExecute = OptIn, but it does not affect the use of dual systems. What does this mean?

　　A:It is generated by another important security feature in SP2, "Data Execution Protection (DEP. You can find it in "Control Panel> system> advanced> Settings> Data Execution Protection. When you switch between the two items, "/NoExecute = OptIn" will also change to "/NoExecute = Optout ". Note: This feature requires hardware support, including AMD Athlon 64, AMD Opteron, Intel's cert and Cert 2, it is said that companies such as nVIDIA, VIA, and quanfang also plan to add the technology to their chips. It is recommended that common users do not modify it; otherwise, the system may be unstable (for example
