Hi, Im working my way through the Microsoft 70-640 Configuring Windows Server 2008 Active Directory Book and have come across something puzzling, because Im sure Im doing everything right and yet it doesnt work. Chapter 5, Lesson 1 - Redirect the default computer container (page 223). I have inputted the command (redircmp ou=Clients,DC=contoso,dc=com) both with and without quotation marks and yet each time I get the same error message : Error, unable to modify the wellknownobjects attribute. Verify that the domain functional level of the domain is at least Windows Server 2003: Operations Error. Redirection was NOT successful I am 100% sure of my domain function level (2008r2 forest and domain) and I am sure that the client OU isnt contained within another OU. Ive had a look at technet and other online stuff and I cant see why the command isnt working. Does anyone have any suggestions? (redirusr command will yield the same results too) (In case its relevent, All my servers are being run virtually on VMware player;my 2 domain controllers are running Server2008R2 Enterprise)

Is there an english translation for the blog you have referenced?

the issue here is that your domain seems to be running at 2000 native. If i'm not mistaken you require at least 2003 domain functional level to make this work. To do this you can open domain.msc (start -> run), right click your domain and select "raise domain functional level". make sure that you do not have any pre-2003 domain controllers in the environment as they will stop working when you make this change. It is a one way change and is NOT undoable...
