Windows Server 2008 and 2003 active directory in same domain

I have two Windows Server 2003 Standard machines that are domain controllers, one in the main office and the other in a satellite office. They are set up for AD replication. I'm replacing the box in the main office with a new Windows Server 2008 Standard R2 machine. The DC in the satellite office will remain on Windows 2003. I found some good instructions here for replacing the main office machine (Q23582347) but haven't come across anything yet about what if anything I need to do to the Windows 2003 box that will stay in production in the satellite office. I need to make sure it remains healthy and I can still replicate AD.

No nothing needs to happen with the 2003 box, it can co-exist nicely with the 2008 R2 DC.

The only thing is that you can't move your functional levels to 2008 R2 until all your DCs are 2008 R2 so you won't get some of the nice features like the AD recycle bin until then.

Thanks

...and for more instructions you can see the links in this question I helped with

http://www.grouppolicy.biz/2010/05/how-to-exclude-individual-users-or-computers-from-a-group-policy-object/

The biggest question we see here is about the adprep for 2008 R2. I'm assuming your 2003 boxes are x32 so make sure to use adprep32 from the 2008 R2 disk.

Thanks

I would have to agree with Mike you would not see any issues with your remote site if it is still running Windows 2003 server.

Here is a step by step guide.

Mike, yes the existing servers are x32. So looking at the steps from Q23582347, I'm going to put the 2008 DVD into the existing 2003 server in the main office and run adprep32 /forestprep and adprep32 /domainprep, is that correct?

well if it is 2008 then adprep  if it is 2008 R2 then adprep32.  Yes run forestprep on your schema master and domainprep on the infrastructure master.

Thanks

Only if the Windows 2008 server is an R2 version if it is not then you would need to use adprep.

Here is a good article on adprep and adprep32

Hmmm...it's Windows 2008 R2 but I'm not finding adprep32.exe under sources\adprep on the DVD.
