SNA Server Manager May Not Find Subdomain When Started

ID: Q196604

The information in this article applies to:

Microsoft SNA Server, versions 3.0, 3.0 Service Pack 1, 3.0 Service Pack 2, 3.0 Service Pack 3, 4.0, and 4.0 Service Pack 1

SYMPTOMS

When starting SNA Server Manager, it may intermittently fail to find the subdomain. This has been observed when Manager is run from an SNA Client computer, which is located on the other side of a router from the sponsor servers. The error message that is displayed is "<subdomain> NOT FOUND." Traces indicate that when the problem occurs, Manager is attempting to locate the servers using local broadcast, which fails because the servers are on the other side of a router.

CAUSE

The SNA Manage Client (Mngcli.exe), which is started when Manager (Snaexp.exe) starts, requires time to initialize. SNA Server Manager times out before the SNA Manage Client can completely initialize, resulting in a local broadcast for any SNA Server computer.

RESOLUTION

SNA Server 3.0

To resolve this problem, obtain the latest service pack for SNA Server version 3.0. For additional information, please see the following article in the Microsoft Knowledge Base:

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):

WORKAROUND

The problem is timing related. Deleting the SNA Server Manager settings file (Snaexp.snav) seems to work around the problem, most likely because the timing of the SNA Manage Client (Mngcli.exe) initialization process is altered.

STATUS

Microsoft has confirmed this to be a problem in SNA Server versions 3.0, 3.0 Service Pack 1, 3.0 Service Pack 2, 3.0 Service Pack 3, 4.0, and 4.0 Service Pack 1. This problem was first corrected in SNA Server 3.0 Service Pack 4.
