Vista - Vista Sp1 Update

Hi
I Have Vista SP1 installed for about 8 weeks now ..and have had no problems
till 2 days ago.
The Vista Update just opens a window but nothing really happens..it never
shows what has updated..and what is available for updates.
The Little timer just goes round and round..I have let it sit for 4 hours
and the same..nothing changed.
It cannot be closed except thru task manager which then opens the look for a
solution box....never finds one...then proceeds to reset Windows
Explorer...Aero shuts down...Screen hiccups for 1/10 of a second...Aero
comes back....
The same thing happens with Defender when I try to manually update...it says
its searching but even after 3 hours its still searching.
I have shut off the ZA Pro Firewall..but that changed nothing..
anybody got any ideas about what is going on and what I could do to
troubleshoot/solve this problem??

problem with the ZA firewall. Turning the ZA firewall off wasn't
enough for some reason - it seems there is some residual behavior.
What did work was going into ZA and resetting everything to the
default settings.

Still, before looking at the firewall, I would try doing a system
restore, hopefully back to the last time you knew that everything was
working.
