ADPREP /Forestprep Issue

Hi everyone,

I am in the middle of doing an Exchange 2003 to Exchange 2010 rollout. My Exchange 2010 HA servers are up and running along side my acient Exchange 2003 server but I am having an issue either installing a new 2008R2 DC or even upgrading an exsisting 2003 SP2 DC to Server 2008.

If I attepmt to upgrade a 2003 SP2 DC to Server 2008 I am greeted with the following error telling me that " Active Directory on this domain controller does not contain Windows Server 2008 R2 ADPREP /FORESTPREP"

I am slightly confused because I thought I had to do this when I installed the Exchange 2010 servers.

So I jump over to my primary DC and run ADPREP /FORESTPREP and I get this message stating that "Forest-wide information has already been updated" and it quits.

I sync all of my domain controllers just to make sure everyone is up to date and I still get the error message when I attempt to update the 2003 server to 2008.

As a side note I have also buit a machine from scratch thinking that mayb e the previous Sys admin's did something funky that is preventing this from happening but I still get the errors.

Thanks for any and all help!

I will give that a shot and post what I recieve.

I probably should have mentioned that all the old servers are 32Bit Server 2003 and my new Exchange servers and the OS I would like to upgrade (Or at least built me my DC's) all the exsisting DC's to is 64Bit Server 2008. When I ran Forestprep I did it off of the Server 2008 32Bit .iso/DVD that I downloaded from MS VL Site. (I found a site that said if I was running 32Bit 2003 I need to run ADPREP from a 32Bit 2008 disk).

KCTS: Thank you very much for the Adprep32 /forestprep command.

That was the winner in going from 44 to 47.

Thanks again everyone!
