Could you not use a keygen or grab a serial from somewhere to get a "valid" key and block the app from the internet via firewall to prevent the check from calling home?

Sorry I'm not familiar with how this specific game checks validity.

Edit: Google pulled up this workaround at https://www.barik.net/posts/multiplayer-neverwinter-nights-on-local-lan/

Simply edit the file:

%windir%\system32\drivers\etc\hosts

and add the following lines to remap the Neverwinter Nights official servers to localhost:

127.0.0.1 nwmaster.bioware.com

127.0.0.1 nwnauth.kr.infogrames.com

I was able to get past the initial key prompt with a key from here: https://alt.games.neverwinter-nights.narkive.com/wcVZcdsd/cd-key-for-nwn

When I try to start the session though, I think it still connects to a server to verify and I'm unauthorized to proceed any further.

I tried adding the changes you mentioned, but it did not work. This is an old game, so maybe it's connecting to a different set of servers for verification. I don't know how to check which servers are being pinged, though.

You might be able to see where a connection is going using the resource monitor in task manager when attempting the check
