Windows VISTA update issue error code 8000FFFF

Hi,
I have a Windows Vista update issue. I have tried to update numerous times without success. Also, when I go to view my installed updates none are present.
When trying to update it does not update and gives an error code of 8000FFFF.
I have been searching for a solution to this problem in the Vista Newsgroups without any success. All I see are obnoxious messages from Microsoft personnel telling people to post their question on Vista website when in actuality that is exactly where they are posting!!
Does anyone have any idea how to solve the Vista Windows Update error code 8000FFFF?
Thanks in advance.
