Domain Migration - Duplicate Computer KDC Errors

Tech-Archive recommends: Fix windows errors by optimizing your registry



We'ved worked through a geographically disperesed migration, over to a
new domain. After doing so we are getting KDC errors for the majority
(if not all) of the servers and workstations that have been migrated.

The original domain is still active and participating as a replication
partner to some of the other servers in the new domain. Could this be
causing our problem? I noticed that after using the ADMT 3.0 to migrate
the user and computer accounts that the computer accounts still exist
in the old domain. Shouldnt these have been removed? Would removing
these form the old domain solve the problem since they are still
replication partners to the new domain?

Here is a copy of the event log, we get an identical log for each
system that has been migrated.
