I setup WSUS in a relatively new network onto Windows Server 2003 a month or so ago. I never ran SUS in our network. All of our clients are running Windows Xp sp2. The configured all my client pcs to use the WSUS server in Group policy. The group policy object for WSUS is enabled and enforced for every pc in at my company.
When I first setup WSUS it was successful in picking up most all the clients. But of my 50 pcs I support only about 30 of them were picked up my WSUS. As far as I can tell there is no pattern as to which clients were picked up by WSUS vs which ones weren't. For example some pcs in the same Organization Unit in Active Directory, the same OS load, and the same hardware...only some of them will be picked up by WSUS. I tried running a wuauclt.exe /detectnow from the WSUS server and the clients and it didn't help. Any ideas?
Also do you know the window/dialog box that pops up after you've installed updates and you need a reboot...the one that asks you if you want to reboot now or later...is there a way to get rid of that? I have some pcs that are running a web application we wrote in internet explorer in kiosk mode...and that windows/dialog box pops up right in front of IE. We are in a production environment so we can only reboot after hours.
