I'm using Windows 7. I'm trying to do remote debugging with Visual Studio 2010 on another computer in the same LAN on a Windows 2003 network, but I cannot seem to connect to the other computer (which is running Windows XP Professional)

I disabled the windows firewall on both computers. It uses port 4015. Is it possible that Windows 2003 blocks the port? The network also has a separate firewall, but I think that's only for internet.
