Looking for lost WinXP firewall

        After viewing the properties of "Local Area Connection" and switching to the "Advanced" tab, the Windows Firewall (ICF) that should have appeared is gone! Instead, a hint: Windows can't display the properties of this connection, how to get back the XP firewall?

The author's Windows XP has a strange problem: After viewing the "Local Area Connection" property and switching to the "Advanced" tab, the Windows Firewall (ICF) that should have appeared is gone. ! Instead, a hint: Windows cannot display the properties of this connection. Windows Management Instrumentation (WMI) information may be corrupted. To correct this problem, use System Restore to restore Windows to an earlier point in time..."

But the author's system has already turned off System Restore after the installation is complete. How is it? The author has made the following attempts in order:

Try 1: In view of the NIC failure, first choose to reinstall the NIC driver after uninstalling the NIC in the Device Manager, and the fault remains.

Try 2: Right click on "Local Area Connection", select the "Repair" command, wait a moment, the system prompts "Repair operation is completed. If the problem persists, please contact your network administrator or ISP. "At this time, the fault still exists, and when you right-click "Local Area Connection" and select the "Bridge" command, the system prompts "An abnormal error occurred while configuring the network bridge."

Try 3: Because of the above two comparisons The conventional solution can't work. Consider reinstalling or repairing and installing Windows XP. However, with the attitude of trying to search for "Windows Management Instrumentation" as a keyword on the search engine, I found a solution. The specific operation is as follows:

Step 1: Right-click on "My Computer", select the "Manage" menu, navigate to the "Computer Management (Local)→Services and Applications→Services" item, and find "Windows Management Instrumentation" in the right window. "One item, double-click to open, click the "Stop" button in the pop-up window.

Step 2: Enter the C:WindowsSystem32WbemRepository directory of the local disk, delete all the files in the directory, restart the computer After logging in, the system will re-create the required files in the directory and automatically start just Stopped WMI service.

Tips
This fault is caused by a corrupted file in the C:WindowsSystem32WbemRepository directory. WMI will call the files in this directory every 30 to 60 seconds, so The above error message is received. Other chain reactions that can be caused by this fault are: unable to view the properties of "local connection", when the msinfo32 (view system information) command is run, the system is not responding, and when the wmimgmt.msc command is run, the WMI management unit is opened. The system prompts "Failed to connect to local computer due to WMI: Generic failure" error.
