Exclusion for a Group Policy Object

I have seen numarous post for a simple GPO query that how do I exclude some users/computers for a Group Policy object.
I have given every screenshot for excluding a GPO.

You have to install the GPMC for 2003 but in 2008 GPMC is available in any DC.

Open the GPMC



Select the GPO


Click on the delegation tab


Click on Advance


Add the user , you want to exclude from that GPO and click on OK



Check the read "Deny" and Apply Group Polcy "Deny" and click on apply.


Click Yes


Click OK


Now that GPO will be not appilied on Harry.

Same thing you can do for computer exclusion
