I have used Autoexnt in the past to do this. It starts a program as a service, then displays the GUI whenever a user logs in.

You can get it from the 2003 resource kit tools

Depending on your setup, you may have to setup dependencies on other services that need to start before your application

It's been a while and I was at a different company, so sorry the details are sketchy. This should get you started though.

>But I was wondering concerning your words about GUI and service. You see I have a small app that does have a GUI part (basically a form with a timer that converts text input into VFP database). The customer asked me to look into converting this application to a service. His reasoning was that often times he reboots the server (where the app resides) and forgets to log in and start the application. He said that if the app would run as a service, no log in would be required.
