Here's a tip:
If everything was working fine, and then suddenly you can't connect to a server, first check if that server is down. If it's not, it's your machine.
DON'T sit there like an idiot and waste two hours rebooting after making minute changes. It worked before...so what did you do?
Me, I kicked it, and knocked the LAN card clean out of it's slot, piece of crap Kayak that it is...
*sigh*
Well, there goes two hours wasted.
