Help regarding delegation of controls in ADS

Hi dears. I have a problem pls help.
Problem is that i m using windows 2000 Server as a DC. I have created a lot of OUs for my work environment,I have successfully delegated different rights to the users relevant to their OU, but when i want to see that to whome i have delegation controls and what controls then nothing i can see, I also want to roll back some controls from delegated users but how all this can be possible. That we can view and change the delegated permissions for users in ADS.
