You want to verify that an application partition is instantiated on a replica server. After you add a domain controller as a replica server for an application partition, the data in the application partition needs to fully replicate to that domain controller before it can be used on that domain controller.
Use the following command to determine if there are any problems with application partitions on a domain controller:
> dcdiag /test:checksdrefdom /test:verifyreplicas /test:crossrefvalidation /s:[RETURN] <
These tests are valid only with the Windows Server 2003 version of
CrossRefValidation tests can help determine if an
application partition has been instantiated on a server and if there
are any problems with it. Here is the
information for those three tests:
This test looks for cross-referencess that are in some way invalid.
This test checks that all application directory partitions have appropriate security descriptor reference domains.
This test verifies that all application directory partitions are fully instantiated on all replica servers.
Another way you can check to see if a certain application partition
has been instantiated on a domain controller yet is to look at the
msDS-HasInstantiatedNCs attribute for ...
