SYMPTOMS
========

After you open SNA Manager and you expand the Microsoft SNA Manager folder, you
may receive the following error message:

   <Error opening sub-domain>

If this message appears, the following event is also posted in the application
log of the Event Viewer:

   Event ID: 5149 - Source: SNA Manage Agent

   Manage base error - error in accessing the domain table. The local domain name
   is not valid

CAUSE
=====

Though there may be more than one reason for this problem to occur, two known
causes are:

 - The Remote Registry Service is stopped or unavailable.

 - The SNA subdomain name is not listed in the registry. This error is seen only
   if the value is blank.

NOTE: By default, the SNA subdomain name is the Windows NT or Windows 2000 Server
name.

RESOLUTION
==========

Resolving this problem involves these steps:

 - Start the Remote Registry Service.

 - Verify that the SnaDomain:REG_SZ: <subdomain_name> value is listed in
   the registry.

To resolve this problem, follow these steps:

1. Start Registry Editor (Regedt32.exe).

2. Locate the SnaDomain value under the following key in the registry:

   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SnaBase\Parameters

3. On the Edit menu, click Multi String, type "<Subdomain_Name>" (without
   the quotation marks), and then click OK.

4. Quit Registry Editor.

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

If SNA Management tracing was turned on during this time, the Expintx.atf trace
file shows that after the MngGetLocalDomain call is made, the value name (SNA
subdomain name) that comes back is <blank>.

   

   mngglobl.cpp(1556) MngGetLocalDomain Local Domain is <blank>
   manage.cpp(443)    CreateDomainManageObject Call to CreateDomainManageObject
   mngglobl.cpp(1556) MngGetLocalDomain Local Domain is <blank>
