Domain / Networking Issue

[ITnoob]

How can I make it so that one single computer (not user) on a domain can bypass the domain settings; An Administrator account.
I need to make it so that when the computer times out after 10 minutes and goes to Screen saver that when I resume, it doesn't go into lock mode. (Alt + Control + Delete etc.)
However, if I change the settings on the Administrator account, it will apply for all computers and the companies security will be compromised.

And I can't remove the computer from the domain either, it's an important system.

Any ideas?

Make another GPO overriding those settings, create another OU in the folder where your computers are currently located, apply the new GPO there and make sure it's enforced so the other default policy doesn't override it. Then drop this specific workstation in there.
