Hi,

We have 2 domain controllers (primary & backup), recently we have moved our backup DC to a new data center.  The 2 DC can ping each other but cannot replicate.  I ran dcdiag and got the attached log from the backup DC.

I have been following: http://www.experts-exchange.com/questions/26318254/Replication-errors-on-new-Windows-2008-RC-DC's.html but still end up with the same result from dcdiag "Got error while checking LDAP and RPC connectivity.  Please check your firewall settings."

Please help.

Sounds like you have your DNS configuration wrong.  The dc should point to itself for DNS resolution.  The net logon service should register the correct DNS records. Then it should be able to find the other server using DNS.  You may need to also check the IT address of you name server in the DNS tab.

Steven,

This is another issue, when we tried to access DNS, there is an error "Access was denied" and when I click add, it gave me a red icon with a server name.

If you are referring to the DNS management tab then this may be pointed to wrong server name / ip address.   I suspect your issue lies in the network adapter settings for DNS. You can also check the services for DNS and net logon are actually running.
