win2k help

i am really confused ???, i am tryign to apply a group policy to a windows 2000 professional client from a windows 2000 server. The server is running a domain and has active directory running.  I can log in in fine and all but the group policy wont apply.  The way i ahve it setup right now is that i have a test user in a dummy organizational unit, and the organizational unit has the group policy applied to it. I tried everything that i can think of, but to no avail.  i tried to block policy inheritance, i tried to disable the default domain policy and use a organizational units policy only but that wont ork either. if anyone out there can offer any advice it would be welcomed and appreciated, thx
