Not allowing administrator priveledges

Archived from groups: microsoft.public.win2000.setup (More info?)

Hi. I went to change the time on my computer while logged
in as administrator and it tells me I do not have enough
priveldges to do this and to log in again as
administrator. My user profile says administrator, all
rights, but the computer isn't recognizing this. Has
anyone else ever experienced this? Can someone help me
with this? Thanks.
