Event ID 1988 Logged in Directory Service Log after Schema Update
Some deleted objects that are nearing the tombstone lifetime may still exist on the source of a replication agreement and have an attribute added to the partial attribute set of the object that should be replicated out. If the same object was garbage-collected on the target domain controller when it was replicated, the destination domain controller logs Event ID 1988 and possibly Event ID 1388.
Windows Server 2008 R2 DNS servers that use root hints are unable to resolve some DNS queries.
