If a directory partition is removed (the last domain controller for that context is demoted to a member server), and is then re-created before replication is completed, lingering phantoms may be incorrectly referred to by a crossRef object. This condition can cause replication errors, and may prevent you from promoting a new global catalog. See the "More Information" section in this article for definitions of terms and sample Directory Services event log entries.
Note that the Windows 2000 Service Pack 3 hotfixes that are listed in the "References" section of this article do not permit the Ntdsutil.exe tool to fix this problem.
The update that this article describes is a preventative fix; the fix is intended only to prevent the problem from occurring.

814202 The Ntdsutil Semantic Checker Cannot Rename Conflict-Mangled Phantom Names
Inbound replication of a new crossRef object is delayed when the nCName value matches an existing object. However, if the nCName value matches an existing phantom, the value may be attached to an old naming context. When later references to the correct (new) naming context are replicated in, the existing name is "mangled" to reflect that it is in conflict.

This is an object that has been deleted, and whose tombstone lifetime has passed. However, references to the object are still present in the directory database.Phantom objects are special kinds of internal database tracking objects that you cannot view through any LDAP or Active Directory Service Interface (ADSI) tool.
These are objects of the crossRef class that identify the existance and location of all directory partitions, and permit domain controllers to be aware of forest-wide directory partitions. These objects are stored in the Configuration container, and are replicated to every domain controller in the forest. Each crossRef object has a "nCName" (naming context, or directory partition) attribute. These must be unique.
Error Message That You Receive When You Try to Promote a New Global Catalog
A request has been made to promote this DSA to a Global Catalog (GC). Aprecondition to becoming a GC is that this server host a read-only copy of allpartitions in the enterprise. This server should hold a copy of partitionDC="domainCNF:old_domain_GUID",DC=com but it does not. This system will notbe 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 replicaof the partition because all of its sources are down. Please check the eventlog for KCC errors.
The KCC will retry adding the replica.
