microsoft.public.windowsupdate

Good Day,

I have just noticed in my WSUS server that it is showing some of my
computers as not being updated for xxx days even computers I know have
just been updated.

Is there a way to force the server to update itself and the true status
of the machines reporting to it?

I have placed the wuauclt /detectnow command in my domain login script
so I know that all the machines are at least once a day reporting to the
server.

Appreciate your assistance.
