Replication is Not Working between DC's

Medium Priority

Last Modified: 2012-05-07
I am a bit of an impatient person at times, so I created a user on one domain controller but it did not replicate this data to the other domain controller.  I went into AD sites and tried to replicate the data, but I got the error that the RPC Server when I tried to replicate data from DC2 to DC3.  When I try to replicate data from DC3 to DC2 I am told that the naming process is in the process of being removed or is not replicated from the specified server.  Both of these computers are Win 2k3 Server R2.  Any help to get the replication working is much appreciated.

Are you able to run DCDIAG on the domain controllers and post the results?

OK, check the DNS entries are right on each server, ensure they are all set to the primary DNS server and can communicate with it.

Then try running DCDIAG /FIX on all DC's

wscal2 that error is just reading errors in the SYSTEM LOG
I suspect your issue here is DNS related, a lot of AD replication problems are.

is the name and address correct in your DNS?
Are there any other entries for either that name with an incorrect IP or the same IP with a different name?

Author

Commented:
There are no other entries for that computer indicating a different IP address.  I looked in the DNS and it appears that everything is correct.

If this record is supposed to exist in DNS under msdcs.westminster.local it does not.  I only see WSCAL2 as being a service location.

also stop and start the netlogon service on this domain controller then run dcdiag again.

Just as both of us suspected, it is a DNS issue, but I do not actually know how to fix this.

That log says it's fixed it try running it again just to check.
Is it definately pointing at the right DNS server?
Does it have an odd DNS suffix in the advanced IP settings of the network card?

Author

Commented:
It tells me that it cannot find an authoritative DNS but then it says that it fixes it, no matter how many times I run it.  There are no advanced DNS settings that are any different.

Is it active directory integrated DNS?
Is it set to allow updates?
You can find out by right clicking on the server in the DNS console and selecting properties

Apparently it just took time.  I rebooted WSCAL3 and it seems like they are successfully replicating now.  Thanks.
