DCA ISCA SDLC Link Service Sets Incorrect Registry Entries

• Microsoft SNA Server, version 3.0

SYMPTOMS

The symptoms will vary depending on whether this is the first link service installed. If this is the first link service installed, most of the registry values will be left empty. Most notably, the DependOnService value for SNAServr will be missing DCASDLC1, which will cause the SNA Server service to start without starting the link service. The server will go to an Active state in SNA Manager, but the connection will not change from Inactive. If a previous link service is installed, the values will be entered, but incorrectly. In this case, the connection will go to a Pending state, but will not establish a connection with the host.

CAUSE

This was caused by an error in the setup file for this link service.

RESOLUTION

A fix has been made to the setup file for this link service.

The current workaround is to use the DCA SDLC link service from SNA Server 2.11 Service Pack 1. To do this, use the following steps:

1. In SNA Manager remove the DCASDLC link service.



2. Copy files from the 2.11 SP1 compact disc to the SNA 3.0 installation folder. Copy these files from the <CD>\I386\System\Hwsetup folder of the compact disc to the <Snaroot>\System\Hwsetup folder on the hard disk:

   Dcasdlc.hlp
   Dcasdlc.srl
   Dcasdlc.inf




3. Create a folder named Dcasdlc in the \<Snaroot>\System\Hwsetup folder of the hard disk and then copy Dcasync.sys from the \<CD>\I386\System\Hwsetup\Dcasdlc folder to the \<Snaroot>\System\Hwsetup\Dcasdlc folder:



4. Run the External Link Service tools from the Tools menu in SNA Manager.



5. Click Add and select "DCA SDLC link service."

STATUS

A supported fix is now available, but is not fully regression-tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix.
