Win95 Client May Trap When Client/Server Encryption is Enabled. (193987)
The information in this article applies to:
- Microsoft SNA Server 4.0
- Microsoft SNA Server 4.0 SP1
This article was previously published under Q193987 SYMPTOMS
SNA Server Windows 95 clients that connect to an SNA Server from a non-
trusted Windows NT domain may generate an access violation in Snakrnl.dll
if the SNA Server is configured to support data encryption for the Everyone
group. This problem has been observed when starting the SNA Server Win3270
tool, which led to the following error message being displayed:
WIN3270 caused an invalid page fault in module Snakrnl.dll at
0137:620867e7.
This problem may occur when running the SNA Server Windows 95 client on
Windows 95, Windows 98, or Windows NT.
CAUSE
Data encryption is not supported across non-trusted Windows NT domains. If
the decryption fails, the received data will be processed as a good
message, which causes an access violation in Snakrnl.dll.
RESOLUTION
Microsoft has confirmed this to be a problem in SNA Server versions 4.0
and 4.0 Service Pack 1. This problem was corrected in the latest SNA Server
version 4.0 U.S. Service Pack. For information on obtaining this Service Pack,
query on the following word in the Microsoft Knowledge Base (without the spaces):
MORE INFORMATION
The updated causes the client connection to be closed. In addition, the
following error message is displayed, "ERROR - Reading SNA Server
Configuration", rather than generating an access violation.
