SYMPTOMS
When you open the Microsoft Management Console (MMC) SNA Manager snap-in, you receive the following error message:

Communication with the servers has been lost. SNA Manager must be restarted.

Additionally, an Event 5149 similar to the following is logged in the Application Event Log:

Event ID: 5149

Event Source: SNA Manage Agent

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



CAUSE
The problem occurs when the SNA Manage Client (Mngcli.exe) process tries to start without having received the startup parameters that it requires to start successfully. This behavior may occur when certain types of applications are run on the same computer that is running Host Integration Server 2000. Antivirus software and system monitoring software are examples of the types of applications that might affect how the SNA Manager Client process starts.



RESOLUTION
If the server computer that is running Windows NT or Windows 2000 is also running any third-party applications, try to determine if one of the applications is causing the problem by removing the applications one at a time.



WORKAROUND
To work around this problem, follow these steps:
 * 1) Open a command prompt.
 * 2) Change to the   directory.
 * 3) Run Snaexp.cmd from the command prompt.
