SNA 3.0 NT Client Setup Sets LanmanServer Dependency in Error

Article ID: 170425

Article Last Modified on 10/22/2003


  • Microsoft SNA Server 3.0 Service Pack 4

This article was previously published under Q170425


When installing the SNA Server 3.0 (or 3.0 SP1 refresh) Windows NT client software, the setup program incorrectly configures SnaBase to be dependent on the Windows NT server service (the LanmanServer service).

While the SNA Server Windows NT client software is dependent on the Windows NT Workstation service (LanmanWorkstation) and Windows NT security provider (NtLmSsp), there is no need for the Windows NT Server service to be running on an SNA Server Windows NT client machine.


This problem was inadvertently introduced in the SNA Server 3.0 Windows NT client setup program. This problem did not exist when installing the SNA Server 2.x Windows NT client software.


WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.

To work around this problem, the DependOnService registry key on the SNA Server 3.0 Windows NT client machine should be updated as follows, using REGEDT32. After initial client installation, the setup program sets the registry entry as follows:

   DependOnService: REG_MULTI_SZ: LanmanWorkstation LanmanServer NtLmSsp

Edit the key so it appears as follows, removing the LanmanServer entry:

   DependOnService: REG_MULTI_SZ: LanmanWorkstation NtLmSsp

NOTE: In the multi-string editor within REGEDT32, entries must appear on separate lines.

This problem will be corrected in future versions of the SNA Server Windows NT client setup program


Microsoft has confirmed this to be a problem in SNA Server version 3.0 and 3.0 SP1. This problem was corrected in the latest SNA Server for Windows NT 3.0 U.S. Service Pack.
