run process on windows server

hi all

in our office we have windows 2003 server for one particular application designed by our team need one service must be running on windows server now when we run process from any user it runs till that user is logged in as soon as he logs off service stops running.
we had win 2000 server there also this type of service used to run even if we log out from that account now we have shifted to win 2003 server .

thanx in advance

Sounds like the service's console handler is not ignoring CTRL_LOGOFF_EVENT.
