XP Automatic Update inoperative

Altho automatic is selected there is no update notified,
downloaded or installed.
When trying to update manually I get the following msg
which stays on forever:
"Checking for the latest version of the Windows Update
software ..."
I have SP1 and want SP2.
Where to look next?
Obrigado.
