Solution for the issue where Windows Server 2003 folders cannot be shared

Today, a very strange issue occurred with Windows Server 2003.

**Symptoms:**

- Network sharing is unavailable, and the Server service cannot be started. When attempting to start it manually, an error "998 - Invalid memory access allocation" and "Service startup error" is displayed.

- However, other services such as IIS and DHCP are functioning properly. A series of troubleshooting steps were carried out:

1. **Folder sharing properties are lost** {the "Use Simple File Sharing" option in folder options cannot be displayed either}.

2. The shared resources of the faulty host cannot be found on the local area network; entering `\\IP Address` fails to locate the faulty host.

3. Network shares configured prior to the fault are lost; in the faulty host, the original shared folder icons (with the hand symbol) are no longer visible.

4. The **Server (C:\WINDOWS\system32\svchost.exe -k netsvcs)** service cannot be started. This service supports file, print, and named pipe sharing over the network. If the service stops, these functions will not be available. If the service is disabled, any services that directly depend on it will not start.

5. The **Workstation (C:\WINDOWS\system32\svchost.exe -k netsvcs)** service cannot be started. This service creates and maintains client network connections to remote servers. If the service stops, these connections will not be available. If the service is disabled, any services that directly depend on it will not start.

6. The **Computer Browser (C:\WINDOWS\system32\svchost.exe -k netsvcs)** service cannot be started. This service maintains and updates a list of computers on the network and provides the list to designated browsing computers. If the service stops, the list will not be updated or maintained. If the service is disabled, any services that directly depend on it will not start.
