Try copying the ds folder to somewhere else and running it. If it works you can just copy that folder to another computer. There might be a standalone version around or that might just be it, I'm unsure.
One remark. I was setting up a dedicted server but my ping times were 5000. This topic has been described a lot, but I cannot set up a dedicated server because of my router. When I plugin my PC directly into my cable modem without a router between them, everything goes fine. Also establish port forwarding of all required ports does not help me. Conclusion: for some reason my Belkin router is outdated.
Yves, I don't think your router is the problem. For some reason, you need to put all the ports in windows firewall exceptions (all the range). Just turn the firewall off won't work, I just don't get it, but it's like that.
To open a range of ports just google it and you'll find it.
Cheers.
Aritan, Well I did actually forward all ports. I did it a lot of times for other software. I also did disable all firewalls. I used even other computers to test... still nothing. But my problem is solved. I noticed that my internet cable connection supports two IP adresses. Now I bypass my router with a switch. Conclusion: my pc is connected directly to my cable modem and everything is ok :dance2:
