I had remote debugger working. I have a set of computers on a private network. I could VPN to that network and debug by launching Visual Studio with the same user name and password as the user on the box I was debugging. This seems to have stopped working. I get an error now about the other machine not being able to connect back to me. I have tried using different machines, and new user names, same results. Did windows updates break something? Any where else to look?
