yes, Microsoft Update is OK, Windows Update is not. I've tried WU a few days ago, seems to be working fine. Now it doesnt work. strange! i've found a KB: http://support.microsoft.com/default.aspx?...kb;en-us;817144 Tried the registry edit, not solved. Maybe my corporate firewall is causing this. Will check with the admin. on other note, MU detected i need 2 more updates for Office 2003. using OFfice Update, it found no updates required. this has always been a conflict between WU/OU -> MU (can't see what WU/OU sees)
