I am having issues with adding my first 2008 server into our existing 2003 AD. here is the scenario :
- 2003 SP2 domain enviornment with 3 existing servers in the same subnet in our main office
- 2008 standrad server is in a different subnet and conected through a 10 MB dedicated MPLS link to main office
- All protocols are allowed , no traffic on the link
Prepared existing 2003 enviornment by running /forestprep and /domianprep switches
I was able to join this 2008 machine to our existing domain as a member , it's using existing DNS servers and can resolve all DNS names .
I log in as domain admin - no issues
I tested quality f link with a ping : Ping -n 32 -l 8096 <hostname> and it was fine. no packet lost.
created a new site and assigned to a 2008 subnet
Then I ran dcpromo on 2008 server to make it an additional domain controller ; it found existing forest , all DCs and started installation of domain controler but it
failed after a few minutes ; here is the error :
Active Directory Domain Services attempted to perform a remote procedure call (RPC) to the following server. The call timed out and was cancelled.
Call Timeout (Mins):
So I thought that RPC gets timesout ; created this registry key (on both 2003 and 2008 machines) : RPC Replication Timeout (mins) and set it to 45 min. Restrated both machines , still getting the same issue .
any suggestions ?
