SourceNTDS Replication
DescriptionPromotion of this server to a Global Catalog has been delayed because partition occupancy requirements have not been met.
A parameter is used to control the strictness that the Directory enforces the partition occupancy requirement. The parameter is
HKEY_LOCAL_MACHINE \ SYSTEM \ Current Control Set \ Services \ NTDS \ Parameters \ Global Catalog Partition Occupancy

The levels are as follows: (0) No occupancy requirement; (1) At least one read-only partition in site added by the KCC; (2) At least one partition in site synchronized fully; (3) All read-only partitions in site added by the KCC (at least one synchronized); (4) All partitions in site synchronized fully.

Greater levels include the requirements of lesser levels. The current occupancy requirement is 4. This server is currently at level 0.
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.
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.
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.
