Check ou this link
http://nwn.bioware.com/downloads/standaloneserver.html. Bioware puts out a NWN server that does not need a cd key. The catch is that is all that it does. There is a linux version also.
If you check the NWN bioware forums which I spent a ton of time on today. You will see that the 1.30 patch will ship with SoU and there is a ton of debate what will happen with NWN non-SoU playing on the new SoU servers. One quote off of there was someone asking what would someone who is not SoU see when a SoU cast a SoU spell. The joking answer was a default badger smacking the person.
I did not see anything about my problem so I am just going to try the 1.29 version and see what happens.
Thanks,
