Group policy settings not being applied

Hi all, Im pretty new to this arena, but here is what I have done….

Set up server 2k3 and an active directory domain, the policy settings were being applied fine before, but now, something is wrong.

It is set to enforced, link enabled, and the OU I created contains the GPO and the only one user it applies to, but the settings are not manifesting at logon, the machine takes ages TO logon, and when I try to do an RSOP on one of the machines I logged into with the domain account, my only options are the administrator acct. and not the domain acct. though the profile is on the machine after logging in.

Does this make sense to anyone? Any help is appreciated all!!!!
THX.
