Changing Link Service Properties Does Not Update the Com.cfg File

Article ID: 172237

Article Last Modified on 7/13/2004



APPLIES TO

  • Microsoft SNA Server 3.0 Service Pack 4
  • Microsoft SNA Server 4.0



This article was previously published under Q172237


SYMPTOMS

When a link service is initially created, the configuration file com.cfg receives a service table update message notifying it of the new link service, as well as a few parameters such as the DLC type and SDLC line type. If these settings are modified later, the changes are not recorded back to the com.cfg file.

Examples:

  • When an Ethernet 802.2 link service is installed, and a connection is created, the property page of the connection in SNA Server Manager indicates an Ethernet link service is being used. If the link service is changed from Ethernet to Token Ring, the conffiguration file com.cfg is not updated properly; therefore the connection still indicates an Ethernet connection.
  • Modifications made to SDLC connections, such as changing the link service from "switched" to "leased" are also not be reflected in SNA Server Manager.


CAUSE

SNA Server Manager is not properly notified of these changes and therefore they are not reflected in the Com.cfg file.

STATUS

Microsoft has confirmed this to be a problem in SNA Server versions 3.0 and 3.0 Service Pack 1 (SP1). This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION

With the fix applied, SNA Server Manager is notified and the com.cfg file is updated when changes to DLC link services are made. Changing an SDLC line from "leased" to "switched" or vice-versa is no longer allowed. Instead, the link service must be deleted and re-added.
