I have an Active State Perl v5.6.1 script running on Windows NT Server that works just fine when I double click on it, however, it has a specific error when it is called via a schedule using Windows NT's AT command.
The error is "System Error 1312. A specific logon session does not exist. It may have already been terminated"

The Perl that is causing the problem is...
system ("NET USER /ADD $theStudent $thePassword");

Normally the NET command can be called in Perl, but it seems that calling the command in Perl via the AT command somehow does not give the same level of system access.

I tried calling the command thus...
system("CMD /C NET USER /ADD $theStudent $thePassword");
but it was the same.

If you have Windows NT / 2000 specific information on why this is occuring, I'd like to hear from you.
