Mixed domain controller setup with Server 2003 SP1 and SP2

By ranj ·
Hi I had a question regarding a domain controller configuration on my network. I had 3 domain controllers on my network they all are on Server 2003 SP1. One of the domain controllers recently failed and I removed the necessary roles of that server before taking it out of production.

Now the server is fixed, I have installed server 2003 and am questioning if I can have this fully patched up with SP2. If I made this server a domain controller like it was before but now with SP2 would that affect replication because the other servers in the domain are still on SP1?#

At the moment the other 2 domain controllers with SP1 have not caused any issues on the network so am reluctant to upgrade to SP2 (if it aint broken don't fix it!)

If anyone could advise me on this, it would be most appreciated.

No difference

The service pack should make absolutely no difference to the domain.

SP2 is no problem.

If the servers are not R2 and you rebuilt the 3rd server as R2 you would need to run an ADPREP first before you did the DCPROMO.

Other than that there is no problem with SP1 and SP2 machines being mixed as DCs.

Have fun.
