I'm not familiar with the AMT reflector ... which tool is this?
From what I can tell, from the .NET exception information you posted, it looks like there is a conflict over TCP ports, when the Socket object is attempting to bind to the port.
Is there a way to specify which port each program runs on? You might want to try defining an alternate port for one or the other.
There is a video here that I think will help you out:
Tim Duncan is talking about how to change the port that the reflector server is running on.
In the server console, remove the 4 default port redirections, and add 4 new ones, such as:
17992 --> 16992
17993 --> 16993
17994 --> 16994
17995 --> 16995
If the server console is running on an AMT-enabled system, then port conflicts could occur by using the default port mappings.
