Description:
Due to an unexpected error, the service fwsrv stopped responding to all requests. Stop the service or the corresponding process if it does not respond, and then start it again. Check the Windows event Viewer for related error messages.

This problem occurs because a pContext pointer becomes null if a connection is notified to close multiple times. This situation causes an access violation in the Wspsrv.exe process.
