After SP2, no more Windows Update

Hi all,

my question is, after I succesfully installed the SP2, when I connect to
Windows Update, I get an error saying that Windows Update cannot continue
since some required services have to be running. These services are :
- Automatic Updates
- Intelligent background transfert
- Event journal
I am completely sure that these are automatic, and running. In fact, I
started ALL services, well almost all of them because there were 3-4 services
which I wasn't able to start, but these really didn't seem linked to the
problem.

Someone here would have an idea?

Maybe to complete, the "automatic updates" in control pannel is set to warn
when there's new updates.

Thanks,
Eric
