Then I suggest you actually take the time to look through your computer settings and other things before you claim a bug in Dom3.
You could have one of the following problems:
- firewall prevents outgoing Dom3 connections
- you have an Nvidia nForce piece of excrement network card that's gone tits up (essentially a severe case of the previous item)
- your connections are blocked by the server (unlikely, as the ping gets through)
- if it's a Windows machine running as server, particularly XP, simultaneous connections may be limited to x and your connection would be number x+1 >> blocked
- other problems related to your internet connection
I work ISP tech support and I have to deal with computer illiterate morons who find it difficult to read the brand name on their PC every day and usually it's something like the above list that causes their problems.
Anyone who knows how to operate a ping command is presumably competent to check firewall settings and other network connection related issues first. If I have to start troubleshooting similar work-related crap here, I'm going to become VERY unpleasant to be around.
One more thing if you have an nForce network card on a Windows machine: Ditch that piece of liquid sh!t as soon as you can and get yourself a proper network card. They are prone to randomly denying some or all outgoing connections when the built-in firewall functionality drivers crap out (they ALWAYS do) and at that point you need either an experienced PC hand to fix it for you, get a new network card or start looking into reinstalling your OS. If it's a laptop with an integrated nForce, you have more limited options and the problem is likely to recur.
