I have a WSUS 3.0 SP2 server that has XP Pro workstations getting updates from it. I have a GPO that specifies that the workstation should get updates from the WSUS server and install them at 3am every day. On the WSUS server, when I set a deadline for an update to yesterday (basically, update the machine immediately), the WSUS policy seems to take precedence. Is this correct?
Also, if I don't set a deadline, is that when the GPO policy kicks in? If so, I guess I don't see the use of having WSUS deadlines for updates, except for the "immediately" options. (?)
