After doing a dcpromo /forceremoval and an update to SP2, one of them screwed up the WSUS 3.0 service. I looked for a solution ton this and on a Microsoft forum an MVP was saying that the dcpromo causes problems. He advised unstalling WSUS then IIS, then reinstalling IIS then WSUS. I tried this and, just like the guy who had started the post, could not uninstall WSUS due to an 'error'. The MVP suggested to the guy to reinstall the OS but this is not an option. Does anyone know how I could either uninstall WSUS or get it working again? There was mention somewhere of permissin to the /WSUS/ folder but I have allowed NETWORK SERVICES full control.
