A request has been made to promote this DSA to a Global Catalog (GC). A precondition to becoming a GC is that this server host a read-only copy of all partitions in the enterprise. This server should hold a copy of partition %1 but it does not. This system will not be promoted to a GC until this condition is met. This may be because the KCC has not run- or that it is unable to add a replica of the partition because all of its sources are down. Please check the event log for KCC errors. The KCC will retry adding the replica.

Explanation

The local domain controller has been selected to be a global catalog. However, the domain controller does not host a read-only replica of the specified directory partition. A precondition to becoming a global catalog is that a domain controller must host a read-only replica of all directory partitions in the forest. This event might have occurred because a Knowledge Consistency Checker (KCC) task has not been completed or because the domain controller cannot add a replica of the directory partition because some source domain controllers are unavailable. Addition of the replica will be tried again at the next KCC interval.
