Where are you in the modules and which henchman are you trying to fire? My recollection was that the henchmen did have conversation options to get them to leave the party, but I might be recalling a play-through using Tony K's AI, which gives more conversation options to the henchmen. BTW, you generally do not want to get rid of henchmen using the radial menu; it sometimes doesn't run the same scripts that the conversation method does and it can leave the henchie unable to be re-hired should you have a change of heart.

HipMaestro's "Henchman solutions" thread in the NWN Official Campaign forum. The thread is focused on the OC henchies, but some of the same issues can crop up with henchmen in any module.
