Two computers on our local LAN, one Win2003 wi. IE6 the other XP Pro SP2 wi. IE7. Start a session on XP, sharing the desktop. Start SharedView on Win2K3, sign in with a second Live ID and attempt to Join the session on the XP machine.
After spinning for a while, Win2K3 comes back and says "This person is not available at this time". Could this be an IP port issue? I didn't see anything in the requirements or FAQ about needing to have certain ports open.
