adprep/forestprep must be run on the domain controller
Posted on 2011-09-17
I've already performed the below prep from the W2K with SP4 which is the existing DC.
adprep /domainprep /gpprep
I'm planning to migrate W2K domain controller into Windows 2008 Server x64 R2, then transfer the FSMO roles: But, when I ran the 'DCPROMO" from Windows 2008 Server x64 R2, a member server, and add it as additional DC, it says that I need to run the "adprep /forestprep" in the domain controller. WHY??? I've already done the preps!
Virtual Network Environment:
DC = Windows 2000 server with SP4 with 32 bit O/S
Ran successfully = adprep /forestprep; adprep /domainprep ; adprep /domainprep /gpprep using the Microsoft Windows Server 2008 Standard x64 Edition DVD
Memberserver = Windows 2008 server R2 with 64 bit O/S (Evaluation version)
Tried running DCPROMO to promote this member server as "additional domain controller"
BUT an error comes up " that adprep/forestprep must be run on the domain controller.
Any idea what's missing or needed to be done so the member server can be added as additional DC, before I transfer the FSMO roles ?
Thanks heaps in advance
