AD REPL ERROR

[Mike]

Have a client who has 4 Branch offices each with a DC.
There are 2 GCs and the rest regular DCs. The 2 GCs are
in different branches. They had misconfigured DNS and
were having issues joining the branch DCs to the Active
Directory Schema. They had different Administrator
passwords for 2 DCs that could not replicate to the
domain. The branches are all connected at 256 or 512
circuits. I changed the administrator passwords to match
the domains and checked all services that run with that
user account and then corrected DNS and successfully
replicated to the rest of the domain. There is still 1
Server that is a DC that will not replicate properly and
is loggin the following event on every server:

Source: NTDS KCC
Event ID: 1550

The site
CN=Manasquan,CN=Sites,CN=Configuration,DC=domainname,DC=com
has no child NTDS Site Settings object. Please use the
Active Directory Sites and Services snap in to create an
NTDS Site Settings object for this site.

I did notice that they deleted the AD SITES AND SERVICES
objects that are automatically created and manually
created one for each branch location...When I try to force
replication I get an error that it cannot replicate
because Replication is busy. When I made a test account
it did replicate to all but the 1 server. Do I just need
to wait til replication finishes? Or does anyone have any
input on what neesd to be done...ANY help is appreciated!!!

THANKS

On the DC that is failing, does repadmin /showreps show a connection
successfully replicating for each of the naming contexts that is the DC is
supposed to replicate? Even when you have a connection object indicating to
replicate from another DC the kcc has to do link translation to setup
repsFroms and repsTos. I don't know how the KCC behaves if the Site
Settings object doesn't exist. I'd make sure it was there. repadmin
/showreps and repadmin /failcache should be able to give you some hints as
to what errors the DC is hitting.
