CAUSE ===== This problem can occur when a RAS client disconnects a RAS connection. When this happens, a port status mismatch may occur between Rasman.exe and Rassrv.exe. When this mismatch occurs, the port event handler is not called and the port is not reinitialized. Because of this, the port becomes unavailable.
