Sender Disconnect Results in Sharing Violations

CAUSE

When a sender encounters a failure to write a buffer to a remote site, and when it terminates due to this error, a single attempt is made to CloseHandle() on the file handle it was writing to. If this handle close fails, entries remain in the session tables of the Windows NT redirector. Minutes later, SMS dispatches a new thread on a retry and the Windows NT redirector returns Error 32 (Sharing Violation) because the session table still indicates that file name has a open in another thread.
