To clarify: it seems clear now that you CAN join other servers, just not ones hosted by you or your friend (despite the username issue - which is something else entirely), as I originally suspected.

As such, hosting a game will require a little more work - as it seems your NAT and NWN don't get along well. Like I said all the way back in my original post, it simply doesn't work in all cases. You will need whoever is hosting to perform port forwarding. Might be worth reading up a bit on this - and using the help given in that guide as a baseline. Remember, where port forwarding is concerened - you need to forward to your hosting machine's INTERNAL/LAN address (not the public facing WAN one). Every computer on your network will have been assigned one. This tells the router to chuck all packets from that port to your hosting machine.

On the seperate issue of your username, it is found in one of the ini files (I am not sure which), check nwn.ini or nwnplayer.ini (Documents > Neverwinter Nights) for it - and change it. This error is likely because another player on the server already has the name OR it's invalid. You may have to try a few. Alternatively (for testing's sake), just try another KNOWN WORKING server.

At least we know now what the problem(s) are. So you should be able to get going now.

Ok, so in a nutshell, what do I need to do?

Hello! Im the friend he was referring to earlier, first of all, I would like to thank you for all the help you have given us!
now on to the issue, He cant join all servers like aribeth, but first time ravenloft seemed to work
(the name issue came later)


QUICK UPDATE : we managed the get the name problem solved, but now the error message " Connection Error : Your CD Key is Unauthorized"
UPDATE ON UPDATE : Removing the CD key file fixed this, we have managed to enter Toms Arena, will start testing other servers

Like I said, we have proved you can access servers, so the remaining issue appears to be that you cannot join a friends game.

We have also proved that you (and/or your friend's) NAT is causing hosting problems. To solve this one you need whoever is hosting the game to forward port 5121 UDP to the local/lan IP address of the hosting machine. After this is done, the host needs to try hosting again and the other joining.

You are welcome, I hope you get it going!

The "Troubleshooting" section of the above guide has a few pointers, much like what I have said above:

Things to check:
1. Have you let the server executable through any firewalls you have (Windows, router etc.)? Remember that Windows firewall has 3 different "profiles" (Domain, Private and Public), so ensure you have the correct ones ticked - or tick them all. Also ensure it is allowed through in both directions (incoming and outgoing).

2. Have you port forwarded all the required ports to the correct internal IP address of the server?

3. Is your server's local IP static? If not, it is liable to change on reboots and mess up your port forwarding rules. You should ideally set it to static to prevent any further changes. Either way, check to ensure your local IP has not altered and subsequently nullified your port forward rules.

4. Do you have any other software (Anti-virus or VLAN software like Hamachi) that could be interfering with network communication for the server?

5. Are you hosting on the same machine you are trying to join the game from? If so you may have a router incapable of "hairpinning". In such a case, connect to it via local IP (using the LAN server browser or manually by LAN IP), rather than external IP.

Aye! We did manage to both join a server it while Buraun hosts, so it must be my NAT or ports.
we still have issues with a few servers, but we will try to figure them out. Again thank you very much for the help! we couldnt have done this without you.

Awesome! Glad you got it going. Have fun!

Hopefully we will :D
