We have had the ADM template in place since August blocking the AU of SP2.
SP2 is specifically not approved on our SUS server. Group Policy dictates
that machines use our SUS server (
http://sus.company.com) for updates. This
has been working since August. Suddenly, starting yesterday or today, we
have seen a huge jump in our Internet bandwidth and now machines are
automatically downloading SP2 from the Windows Update site(s).
I have checked at least one of the machine. The
HLM/Software/Policies/.../WindowsUpdate registry key is set to 1 (to block
SP2), the domain policy is set on the machine and applied (used GPConsole to
verify). Why are our machines now
a) downloading SP2 from external Windows Update
b) downloading SP2 from AU with the blocker set
