Program Group Control Requires Logon Validation (129232)

SYMPTOMS

When a Systems Management Server version 1.0 client (such as Windows 3.1 or Windows for Workgroups 3.11), runs SMSRUN16.EXE and the Program Group Control (PGC), APPCTL16.EXE is called. One or all of the following error messages may appear if the client user is not logon-validated by the Windows NT domain controller:

PGC-Could not enemurate applications in applications database.
PGC-Application database gave error 20
PGC-Could not find object application list in application database.
PGC-Could not complete the updating of the program configuration, contact admin.

CAUSE

This problem occurs because the API call used to determine the global group membership fails when the user has not been validated by a domain controller. This most commonly occurs on clients that are located on the other side of a router from a domain controller and therefore cannot locate a domain controller to be validated. Real mode TCP/IP stacks that cannot use the #DOM: entry in the LMHOSTS file encounter this error when they are located across a router.

WORKAROUND

To workaround this problem, ensure users are validated by a domain controller when logging into the network.

MORE INFORMATION

For the Program Group Controller to determine the user groups the logged-on user belongs to, it must contact a domain controller to obtain the list of groups. This will likely be the same server in the domain that validated the logon request, so if the logon is not validated, the group list will likely not be obtained either. To ensure the users group memberships can be obtained by PGC, please ensure the user's logon request is validated by a domain controller.

STATUS

Microsoft has confirmed this to be a problem in Systems Management Server versions 1.0, 1.1 and 1.2. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
