Autoexnt.exe - AutoExNT Service
The AutoExNT Service allows you to start a custom batch file, Autoexnt.bat, when you start a computer - without having to log onto the computer on which it will run. AutoExNT includes an /interactive option (analogous to the /interactive option of the AT command) that allows you to see the processes started. To use AutoExNT, you must be running Microsoft® Windows® 2000, Microsoft® Windows NT® version 4.0, or Microsoft® Windows NT® 3.5 or later.
