Hi all

I am trying to get a Windows 2008 Server to become a 2nd DC in my SBS2003 network.

I have raised the domain function level to 2003.
I have run adprep /forestprep on the SBS Server
I have run adprep /domainprep /gpprep on the SBS Server

When I run dcpromo on the 2008 server it keeps telling me I need to run adprep /forestprep...What have I missed?

What media did you use to run the prep on the SBS?

You will need to use the adprep that is on the 2008 CD.

I copied over the adprep folder from a 2008 image I had.

All adprep commands completed without errors.

Midway through the dcpromo process is when it gives that message...

The 2nd server is on a different site connected via a VPN but I dont think this is the issue as I have full communication to the SBS Server (IPSEC VPN) and the DNS IP of the 2008 is set as the SBS Server.

Is it a WIndows 2008 Image or Windows 2008 R2 image?

You shouldn't copy it over becase there is always a chance you will miss something, follow the steps in my guide and see if that helps.

Oops...

Ok, details.

The 2008 Server is Enterprise Version, x64, R2.

The adprep I copied over was from 2008 Std.

When I look under "Sources" on the Enterprise version I dont even see adprep.

Have I properly messed this up?

Follow my guide, it's all there in steps 1 to 4.
With Windws 2008R2 you need to use ADPREP32.  The Windows 2008 (non-R2 ADPREP is different and will not work for R2)

Ok I found the right adprep, and the files inside are different sizes!

Can I re run adprep with the right files or will it tell me its already been run...?

Yes, you can re-run the commands, but as I said, it's ADPREP32 with Windows 2008 R2, see my guide, it makes it easier when you see them listed.

Bingo.

Its now asking me to choose a site - should I cancel DCPROMO and create a 2nd site first, as this is physically a seperate site?

You should ideally create a seperate site, subnet and inter-site connector but you can do that after the server has been added to the domain and then move the new DC in to that site.
