I can connect to wsus fine from my admin console but another user on a different subnet cannot. He's in a different section of the building that is basically a seperate network as far as subnet and the network managment goes. We are on the same domain though.
He gets the 'server may be using another port' error when trying to connect and he says it started about a month ago. I can connect fine. He's not being blocked by anything since he can telnet into the server using the wsus port.
