Hi, Are these machines logging onto a domain? If they arn't then try the autologin feature built into XP. Start Run type "Control userpasswords2" press enter If there is a tick in the top box then take it out, click apply then specify the account you want to log on with, they then have no choice but to use the account you have created, unless they logoff of course then log in as who they want to but would they do this? Hope this helps. scott
