Nwn.ini

nwn.ini is a config file for Neverwinter Nights, found in the NWN directory.

Some useful settings you might want to add:

[Display Options] FullScreen=0 AllowWindowedMode=1

This allows you to use Window Mode

[Display Options] Disable Movies=1

This allows one to skip the intro movies.

Note in both cases, one just wants to add to the [Display Options] section, as it should already exist.
