Big problem is solved by hand. Recover lost Win XP firewall

        I have a strange problem with Windows XP: After looking at the "Local Area Connection" property and switching to the "Advanced" tab, the Windows Firewall (ICF) that should have appeared is gone! Instead, a hint is: "Windows The properties of this connection cannot be displayed. Windows Management Instrumentation (Windows Management Instrumentation Component WMI) information may be corrupted. To correct this problem, use System Restore to restore Windows to an earlier point in time..." (see Figure 1).

However, the author's system has already turned off the system restore function after the installation is completed. How is this good? The author has made the following attempts in order:

Try 1: In view of If the NIC is faulty, first choose to reinstall the NIC driver after uninstalling the NIC in the Device Manager. As a result, 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 contact the 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 the above two conventional solutions can't work, consider reinstalling or repairing Windows XP, but with the attitude of trying to use "Windows Management Instrumentation" as a key word Search on the search engine and find a solution, as follows:

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

Step 2: Go to the C:\\Windows\\System32\\Wbem\\Repository directory on the local disk. After deleting 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 the WMI service that was just stopped.

Tip:

This fault is caused by a corrupted file in the C:\\Windows\\System32\\Wbem\\Repository directory. WMI will call this directory every 30 to 60 seconds. The file below, so you will receive the above error message. Other chain reactions that can be caused by this fault are: unable to view the "local connection" attribute, the system does not respond when running the msinfo32 (view system information) command, and the system prompts "Failed to connect to" when the wmimgmt.msc command is run to open the WMI management unit. Local computer due to WMI: Generic failure" error.
