It's probably not a good idea to disable the firewalls at your workplace. You could end up getting in trouble if anything happens. Instead, you should configure the firewalls to allow Limewire access to the internet. It's best to have only one firewall active, as multiple firewalls can actually result in less security. However, as you are at work, I can't recommend that you meddle with things.

You could try port-forwarding your router:

Port Forwarding for the Sonicwall TZ-170

Windstream could be using a firewall...see this link:
