Check your Firewalls on all machines involved. try without the firewall just to make sure it's not the problem.
If you're working from behind a router, you really don't need any other software firewall, as routers have their own firewalls that do not affect the LAN machines behind it.

EDIT
Also there's a "zone, zones" thing - look at your table "launcher" and make sure it says the same thing you are launching with the launcherexecutable.
