WSUS SP1 is installed on Windows 2003 server. Synchronizes ok. All clients report fine. GP is set for option 4-download and install at 2am when no one is logged into the workstations. I can install updates manually by going to MS windows updates on the clients. Reports shows what is needed and I also have the options set to automatically detect and install select criteria such as: critical and security updates, service packs, Office service packs and updates. What am I missing? This is worth 500 points.
