So, Laura say, that they can. 
When I ask - HOW, she point me to the Windows NT 5.0 beta 2 Group Policy
Guide  (http://web.mit.edu/pismere/zaw/group-policy-white-paper.doc) and
HKLM\Software\Policies\Microsoft\Windows\System\DisableGPO parameter.
After some testing I found that DisableGPO have no effect. "Computer
Configutaion" part of policy still applied OK even DisableGPO=1 (so we
can overwrite it). Tested on W2K3 member server.
I think, that this and old solution that been replaced with "Group
Policy loopback" parameter.  

But I can be wrong.

Administrators _can_ disable some settings by direct modification of
registry, but can't prevent can't prevent group policy application.

I hope...
