A domain cross-ref has no SID in it's nCName attribute.

Cross-ref DN: %2

nCName attribute (Partition name): %1

The SID has not replicated into this DC.  Check that replication is succeeding between
the first DC in the Domain who's SID is missing and this DC.

If the Domain was created with a Windows 2000 DC and all member DCs of the domain are
unable to replicate outbound because of Schema Mismatch errors, then all member DCs will need
to have Window's re-installed and the Domain will need to be manually removed using 
meta data cleanup in ntdsutil.exe.

If the Domain was created with a Windows 2000 DC, then replication can be blocked from one DC
to another with "Replication Access Denied".  If replication isn't succeeding between the first DC
in the Domain who's SID is missing and this DC due to a different domain cross-ref missing
a domain SID in it's nCName somewhere else in the forest, then you may need to manually
reconfigure the topology to bypass the blocking replication.
