I have a Windows 2000 SP4 Domain Controller and am trying to prepare the forest and domain for a new Windows Server 2008 R2 server which will become the domain controller. When I run adprep32 /forestprep I am getting the following error:
"Adprep was unable to retrieve information from the local active directory domain controller
Verifiy that the local directory object exists and is accessible.
Adprep encountered a Win32 error.
Errror code: 0x547 Error message: The parameter is incorrect."
This is the only DC in the environment so it holds all FSMO roles.
I have attached the adprep log file.
