my weekend got ruined by MS update KB2533623; after the update on the SBS 2008 SP1 server (virtualized on Xen 5.0.3); the shadow protect service wont start; un-install; re-install with different versions ; no luck;

those two links above lead me to un-install KB2533623; oh dear ; its that simple, had I known all that before hand.
