Hi Jorge,
Thanks for you quick answer.
Actually, I could not find _msdcs.domain.com, and all the others subfolder
under child domain DNS forward lookup zone, how can I get all the
_msdcs,_sites,_tcp,_udp back in child domain DNS forward lookup zone.
Thanks again for you help

Ok, after I re-read your post I noitice that the failures are regarding to a.
old DC GUID correct?
Do you have the _msdcs zone in the child domain?
Can you confirm if the old GUID for DC1 is there (is CNAME record and it's
under _msdcs.domain.com, and you can confirm the GUID for that DC under NTDS
Settings for that DC in Active Directory Sites and Services)?
Assuming that the GUID that the DC2 is trying to use to replicate no longer
exists, you may try to delete that old/invalid GUI and recreate a new CNAME
for the correct GUID, then try replication on the DC2.

Hi Jorge,
Before I upgrade the schema version to windows 2003 R2, even " Last
success @ 2006-05-09 08:48:13" , I still can move accounts between child
domain and parent domain, but after upgrade forest to 2003 R2 schema
version
31, the child domain can not replicate with parent domain as the schema
version still at 30, we have about 10 users in that subdomain, is there a
way
to delete the users from subdomain, and create with the same name as they
used before in parent domain, we need demote the child domain from forest.
Thanks

Hi
Unless you have a uge default tombstonelifetime in your forest this "
Last
success @ 2006-05-09 08:48:13" means that your child domian is dead to
the
forest.
Now the only option is to manually remove it from your forest and rebuild
it
again from the beginning.

Hi Guys,
we have an AD contain 5 subdomain, 20 days again, I tried to upgrad a
Windows 2003 R2 server to DC, which it need upgrade the forest, then I
run
adprep /forest on the DC1 which is schema master DC, the system upgrade
the
schema to version 31 on 4 subsdomans except one domain COS is still
version
30, then the AD replication betwenn COS DC2 to main domain stoped. and
DC2
is
the only DC in the subdomain of COS. our plan is merge subdomain COS to
main
domain, but now the AD stop replicated between those 2 domains, any
action
I
did on the COS domain could not replicate to main domain. the following
is
the repadmin /showrepl on both DCs, please help me the fix this issue
ASAP.
please note, the GUID for schema master DC1 is different from the
result
of
two DC, we rebuilt our DC1 last year, looks like the DC2 still has the
old
DC1 GUID. so, How can I simply change the schema version to 31 on COS
DC2,
and how can I easliy let COS DC2 know the DC1 has differrent GUID.
