Every time I attempt to play multiplayer, it shows me the "Connecting to Master Server" message for a few seconds and just fails. I've disabled my software firewall, checked my Internet connection and everything, but it refuses to work. It's been like this for weeks. I've connected my computer directly to my DSL modem and used Windows XP's built-in PPPOE driver to see if my router was the culprit, but I still couldn't connect. ...help?

Have you checked the hosts file in system32/drivers/etc to check and see that the master server IP is correct?

Do what he said ^

Doh! Of course...I had changed the LFS server IP in the hosts file for a previous version of LFS.

Now that you reminded me, I removed the entry and it's now working. Thanks!
