Active Directory Domain Services attempted to add a crossRef object, but the directory partition name reference (nCName attribute) conflicts with another object. This could have occurred when the crossRef object was added or deleted, the directory partition was deleted, and the crossRef object was added again. 
 
CrossRef object: 
%1 
Old directory partition name: 
%2 
New directory partition name: 
%3 
 
Active Directory Domain Services attempted to correct the name reference, but the operation failed. 
 
User Action 
Check the Partitions container to see if there is more than one crossRef object referring to the same directory partition name. If so, remove one of the crossRef objects. If the remaining crossRef object is in the conflicted form, it will be necessary to run Dsdbutil semantic database analysis to correct the name reference.
