Problems to change npc

I have a problem on having changed the name of the npcs, since I do it from the base of information, but on having restarted the server does not change the name of the npcs :(

had the same problem :P ... u need to change the names in DB and in npcname-e.dat

open your navicat, go to npc.sql table, find the npc's id, change his name/title in that row, but dont forget to change serverSideName and serverSideTitle to 1, you will find both of them in the end of the line.
