Directory replication service failed

[Jessica]

Recently I installed an additional domain controller
(serverB) for an existing Windows 2000 DC (serverA). Then
I changed the roll of the serverB as a GC server. AFter
working for 2 days, Active Directory replication failed
and gives error of "RPC server unavailable..." when I try
to force run replication from AD Site and Services. I
checked all the DNS configurations in the serverA as
mentioned in some microsoft knowledge base site and
worked around, but it did not work. DNS communication
seems to be fine as I can ping server.domain.com to each
other from any computers in the network. ServerA is
running ex5.5 and serverB e2k (newly installed)in the
same site and both are working fine for inboud and
outbound mails.

I will highly appriciate any suggestion to overcome this
problem.

Are both DCs configured to query the same DNS server that hosts the domain's
SRV records?

Yes, they are configured to query the same dns server
which is located at serverA.

Tell me why you changed the GC role.

Tell me why you wouldn't just make each one a GC.

The main domain controller i.e existing ex5.5 server was
working for GC before. I changed the GC role as I could
not install ex2k in additional domain controller without
changing the GC role as suggested in different
worksgroups.
If I make each one GC, will they work as a independent
active directory service? Won't it give any problem in
future?

Thanks
