A few people have had trouble with Satellite connections, your LW default port is blocked by something.

Just double check all your Norton settings, it might be worth your while to even reconfigure Norton from scratch.
Reconfiguring Norton Firewall

Check the thread below, see if the Windstream firewall mentioned there is part of the problem (it may not be, as this person didn't have a satellite connection, but it's worth checking anyway).

I'm not sure about Windstream's p2p policy for satellite connections, their acceptable use policy doesn't say anything specific about p2p use.
You could try changing ports within LW. Tools > options > advanced > firewall config...change the port to 64049. Also change any ports allowed through devices or firewalls to the same number...see if that helps at all.

What brand is your modem?

Otherwise, you might have to call Windstream & ask why port 6346 is blocked & find out their polick on p2p use
