I want to raise my forests functional level from 2000 to 2003. It is a very simply lab deployment, one GC and one DC, and one domain already at domain functional level 2003. There are very few lab users and no real activity. If I am selecting "Raise Forest Functional Level...", then I can properly see Current forest functional level: Windows 2000. I choose 2003 as the new functional level and click "Raise" and after some seconds I am getting error message "The functional level could not be raised. The error is: The directory service is busy." Can anyone please help.
