Hi Sheweiry

This link gives instructions on how to configure the most common types of Firewwalls.
http://www.limewire.com/english/content/firewalls.shtml

Symantec/Norton suggests you not use 2 firewalls as they tend to conflict with each other. Edit Note: your WindowsXP sp2 has a firewall.

If configuring the firewall doesn't help you may have to forward a port on your modem/router. You can find instructions here on how to do this. http://portforward.com/routers.htm

You will need to find the modem/router model no. when you get there.

You can find the Java Version by doing this in LW help>About LimeWire.

Hope this helps.
