Hi guys,

We are moving to a new location. I have new 2x Dell R310 (1 mail server, 1 accounting server) and 1x R610 (file server) hardware on the way. Both will run 2008.

In our existing domain, we have 1 2003 R2 file server, and 1 2000 MDaemon mail server. They are running AD Integrated DNS. Both are DCs.

I believe if I keep the existing domain as is with the new servers as members, that would be the least work. But, if I set the new Dells as the DCs, that means more work.

What do you think is the best setup and procedure? I am fairly new to this so please give specific steps to follow. If I missed an option or you need more info, please let me know.

Thank you,
Chris

Yes you could just ass the 2008 server(s) as member servers - and that would involve no more than adding them to the domain as you would with a workstation.

If you want to make the 2008 Servers DCs then its a little more involved

First you have to extend the schema to allow the 2008 DCs to function - this is done by placing the 2008 DVD in your existing DC and running ADPREP. Put the 2008R2 DVD in the 2003 machine and run ADPREP from the \support\adprep folder. (or ADPREP32 is your machines are currently 32bit)

You need to run adprep /forestprep on the Schema master
adprep /domainprep on the infrastructure master
adprep /gpprep on the infrastructure master

see http://www.petri.co.il/windows-server-2008-adprep.htm

Once ADPREP is done, use the Sever manger in 2008 to add the Active directory Role, then run DCPROMO to make it a DC.

KCTS,

Hi! Thank you for your fast response.

I forgot to mention: We also have a DHCP server. Would that affect your solution in any way?

BTW: Should all the DNS, DHCP servers be combined into one physical server? Is there a best practice to follow? We are a small shop of about 60 users.
