IBM Twinax Link Service Install Failure in SNA Server 2.11 SP1

• Microsoft SNA Server, versions 2.0, 2.1, 2.11, 2.11 SP1
  on the following platforms: NT

SYMPTOMS

When you try to start the SNA Server service in SNA Admin, the status may go to Pending and back to Inactive. The System Event log may also contain the following Event ID 7001 message:

The SnaServer service depends on the SnaTdlc1 service which failed to
start because of the following error: The file could not be found.

CAUSE

The IBM Twinax Link Service is not installed properly if you install SNA Server 2.11, then update immediately to SP1 without first installing the IBM Twinax link service, or installing from the SNA Server version 2.11.sp1 compact disc.

The files: Ibmtdlc.sys and Snatdlc.dll are not copied into the \Sna\System directory from the \Sna\System\Hwsetup\Ibmtdlc directory.

NOTE: This does not occur with other link services, such as the Andrew Twinax Link service or the Barr SDLC Link service.

WORKAROUND

Either copy the Ibmtdlc.sys and Snatdlc.dll files into the \Sna\System directory or remove and reinstall the IBM Twinax Link Service.

STATUS

Microsoft has confirmed this to be a problem in SNA Server version 2.11.sp1. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
