I am trying to use the ANTS Profiling service to profile a .NET web app (on
my machine). I have XP SP2 with the Firewall turned off (my company's
security policy sets this). I have talked to ANTS support, but they have no
idea. The service is running and listening on port 8087 (as expected).

I have tried connected with localhost, my machine name, my ip address, and
always get the same error. The .NET web app runs fine and is also
debuggable (all on port 80). I am using .NET 1.1 I am curious as to why
IPEndPoint address is null:

Here's my log:
