I had some trouble to let ASSAP autostart in Windows Server 2003.
I solved this problem by creating a simple Batch script.

C:  Will navigate to the harddisk were the script is located.
cd C:\ASSAP\ Will navigate to the folder were the script is located.
C:\perl\bin\perl.exe assp.pl Will execute the script.

Save the script with any name you like, it must end with .bat, for example ASSP.bat

For the latest part create a new schedule with the windows schedular and let this script execute everytime windows starts.
