MMC - Users & Computers - Delegation - This function is not supported on this system
Server 2008 R2
XP Clients with Adminpak installed
I'm trying to give a teacher access to change group membership of pupils to allow banning of internet access. I delegate control to her. Made an MMC with only the part of the tree she has access to. Changed out of Author mode. But when I try to run the MMC under her account I just get "This function is not supported on this system". When run under an admin account (or elevated using "Run as") its fine.
Is there anything I've missed here?
