-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft SNA Server, versions 3.0, 3.0 SP1, 3.0 SP2, 3.0 SP3, 4.0, 4.0 SP1 
-------------------------------------------------------------------------------

SYMPTOMS
========

Specifying a SNA Server subdomain or server name that contains a backslash (for
example, \\server\1) in the Open Subdomain option in SNA Server Manager causes
an application exception in MngCli.exe. The application exception causes an
Drwtsn32.log to be generated if Drwtsn32.exe is configured as the default
debugger on the SNA Server computer.

CAUSE
=====

The Manage Client (Mngcli.exe) does not properly validate the subdomain or
server name if it includes a backslash ( \ ).

RESOLUTION
==========

Microsoft has confirmed this to be a problem in SNA Server versions 3.0, 3.0
SP1, 3.0 SP2, 3.0 SP3, 4.0, and 4.0 SP1. We are researching this problem in SNA
Server version 3.0 and will post more information here in the Knowledge Base as
it becomes available.

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):

  S E R V P A C K


WORKAROUND
==========

Do not use a backslash in the name after the initial backslashes ( \\ ).

MORE INFORMATION
================

After you applying the Service Pack, the Manage Client validates the name, and
if a backslash appears after the first two backslashes, it is replaced by a
terminating NULL, and everything after the backslash is ignored.

The Dr. Watson will look similar to the following:
