We have an environment setup with WSUS configured for our machines on a Window 2003 Server. We can see our machines as Clients to the server however there is a large portion of them that do not consistently report. Some may be machines that are no longer part of the domain which I believe I need to just delete however there are many that I can connect to and when I run the wuauclt /reportnow command it does not seem to provide any results. The machines can ping the WSUS server however when I run the client diagnotic tool it reports that the server is not set through Policy, "UseWuServer value is missing". What is the best way to resolve this as it seems to have no problem on some machines and this machine has reported and updated in the past.
