I have a single server windows 2000 domain that I am trying to upgrade to Windows server 2003 R2. The 2000 server has service pack 4 and I am using the and account that has schema administrator access. When I run adrep /forestprep, I receive an error message:
Adprep was unable to complete because the call back function (null) failed.
Error message: CSV file C:\WINNT\system32\debug\ad
