When you try to migrate Windows XP SP 2 computer with ADMT, the migration fails and the error "ERR2:7711 Unable to retrieve the DNS hostname for the migrated computer 'v-test-mig.source.com'. The ADSI property cannot be found in the property cache. (hr=0x8000500d)" is logged in the migration log.

Make sure that the patch discussed at http://support.microsoft.com/kb/944043 is installed on the target XP computer and start the migration of computer again.
