SourceNTDS Replication
DescriptionPromotion of this server to a Global Catalog will be delayed for 30 minutes. This delay is necessary so that the required partitions can be made ready before the GC is advertised. The operations that will occur during this time include the KCC being run to generate the new topology, all read-only partitions in the enterprise being added to this server, and the contents of these partitions being replicated into this system.

If you wish to promote the GC immediately without enforcing this precondition, set the registry variable
HKEY_LOCAL_MACHINE \ SYSTEM \ Current Control Set \ Services \ NTDS \ Parameters \ Global Catalog Delay Advertisement (sec)
to a DWORD value of 0. The GC will be promoted on the next attempt to check preconditions. This value can also be set to the maximum number of seconds that the DSA will wait before promoting to a GC.
Event InformationYou cannot promote a Microsoft Windows 2000-based domain controller to a global catalog server. When you try to assign the role of global catalog to the server by clicking to select the <strong class="uiterm">Global Catalog</strong> check box, events that are similar to the following may be logged repetitively in the Directory Services log in Event Viewer.
CAUSE:
This problem may occur if no domain controllers are available for a particular domain. The problem occurs because of Active Directory directory service replication issues.
RESOLUTION:
To resolve this problem, you must investigate and resolve the Active Directory replication issues. You can use the information in the error messages to help troubleshoot the problem. For example, you may be able to use event ID 1559 to identify the domain partition that cannot replicate.
Additionally, you may be able to use event ID 1265 to determine the cause of the replication failure for the same domain partition.
