Windows NT Fails Because of an Access Violation in WINLOGON (136336)
The information in this article applies to:
- Microsoft Windows NT Workstation 3.51
- Microsoft Windows NT Server 3.51
This article was previously published under Q136336 SYMPTOMS
If an access violation occurs in WINLOGON, an updated DrWtsn32.LOG appears
in the %SystemRoot directory and the following symptoms also occur
sporadically:
- A STOP 21a message appears on the server screen.
- The error message "Error 1723 RPC Server too Busy" is returned to client
requests.
CAUSE
Winlogon fails due to an access violation caused by an RPC length pointer
that refers beyond the end of a data structure (RPC buffer) referenced
during RPC unmarshalling. This occurs if a client program provides an
invalid RPC packet length or the length field gets damaged during the
delivery to the server process.
The STOP 21a message occurs if the security system fails.
The Error 1723 occurs if threads in the SERVICES.EXE block as a result of
the security system failure.
RESOLUTION
To correct this problem, install the latest U.S. Service Pack for Windows
NT version 3.51.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51.
This problem has been corrected in the latest U.S. Service Pack for Windows
NT version 3.51. For information on obtaining the Service Pack, query on
