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:

Start Registry Editor (Regedt32.exe).
Locate the SnaDomain value under the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SnaBase\Parameters
On the Edit menu, click Multi String, type <Subdomain_Name>, and then click OK.
Quit Registry Editor.
