Please help! Windows 2000 security policy problem??

I have administrator rights on my 2000 pro machine and last night I tried to access the local security policy in admin tools but i get this error message for account policies and local policies....??

Windows cannot open the local policy database.

Access to database has been denied.

I checked the permissions in regedt32 and for the properties (permissions) of local security policy... I have full control on everything If anyone here can offer any words of advice it would be greatly appriciated... Or if anyone knows a way to start my security policy over without reinstalling the root. I don't know i've been up too long tryin to figure this out... crap Thanks for your time.....

 

I'm not at my 2000 mochine at the moment....but perhaps the below link will help ?
