Administrative Rights

I am looking for an alogrithm that will allow me to execute a program or installation using a different NT Domain account. The purpose behind this is to write an application that can execute anything under a different account regardless of who is logged on. This is SMS'ish in its behaviour. If anyone can shed some light on how this can be done it would be very much appreciated.

sounds like you are trying to write a service, i.e. a program that can run without a user being logged in.
Be aware, that MS does NOT recommend to write services in NT.
If you are not intimidated by that :-)
read MSDN article Q175948.
It has all the details, including source code...
