When adding a Server 2008 R2 domain controller a 32 bit 2003 server the command “adprep /forestPrep” needs to be run on your 32 bit server. The adprep program comes on your 2008 R2 DVD but when you run this on your old 32 bit server you get an error:

Once i the server join the domain, i try to give a dc role but as i dcpromo.exe it goes to the proccess but i must adprep /forestprep the systems. I don't know how to or which server is need to be adprep. The 2008 server would is part of a windows 2003 server enviroment. I need help with the process i have try all the step require ect.

(this is a dvd - I've seen a lot of references to using adprep from the second cd - there's only one) The first oddity I saw was that Adprep doesn't display any initial text when executed on the existing win2003r2 DC for. ADPREP is broken down into four stages with Windows Server 2008, instead of the two that most of you may be familiar with when you upgraded to Windows Server 2003.

The image file C:adprepadprep.exe is valid, but is for a machine type other than the current machine.

This error was obviously from trying to run 64 bit code on a 32 bit machine. What to do? I googled hoping to find a 32 bit adprep I could download and found a number of posts saying to download a 32 bit version of server 2008 and run the adprep program from there. That seemed crazy so I kept searching.

I finally found that I already had a 32 bit version of adprep. The location is cdrom:supportadprepadprep32.exe on your Server 2008 DVD!

ADPREP Windows 2008 R2 Server into 2003 Domain

After finishing the migration of a client to their new cloud-based Line of Business SaaS application, it was time to finally get rid of the last Windows 2003 Small Business Server that we manage. The client had a Windows Server 2008 R2 Standard server that used to be the database server for the on-premise application which was being re-purposed as the new Primary Domain Controller (PDC) for the domain. After installing the Active Directory Domain Services (ADDS) role on the new server, I went to run DCPROMO on the new server and found that it asked me to run ADPREP /FORESTPREP on the domain. Took me a little bit of searching to find the Windows 2003 Server media and ran the command successfully, but this did not do the trick – turns out I needed the Windows 2008 R2 Server media and run the ADPREP32 command several times to complete the domain preparation for the new server to be DCPROMO successfully. Extracted the support directory from the media ISO to a folder on the root of the old Windows 2003 Small Business Server and then ran the following commands in order:

ADPREP32 /FORESTPREP

This one took a long time as the server was going from Schema 31 to Schema 47.

ADPREP32 /DOMAINPREP

This one stated that I needed to run the next command, so I did.

ADPREP32 /DOMAINPREP /GPPREP

The command actually stated that the update was already applied. Social club dll download mediafire. So went back to the Windows 2008 R2 Standard server and ran DCPROMO again which told me that I needed to run one more command.

ADPREP32 /RODCPREP

Ran this one even though I had no plans of having a Read-Only Domain Controller (RODC) in the domain. After all these commands the new server was able to be DCPROMO into the domain controller role. Now all that is left is FSMO roles, DNS, DHCP, printers and file shares.
