Been logging into a Windows work server from home from my Snow Leo Mac using Remote Desktop Connection but it suddenly has stopped working. This is the message from the IT guy at work: "I can tell you that the lack of connectivity is on your end. Your router/firewall is blocking port 10422. TCP and UDP port 10422 cannot be blocked on your end." I have no idea what this is or how it happened. It was working fine until a few days ago. The only thing that's been done is that I unplugged my AEBS-AC for about half an hour to deal with a slow Xfinity connection. After that, this problem seems to have occurred. I don't know if it's coincidence or if they are related. I have little network experience or skills so I don't know how to resolve this. Any suggestions? TIA.
