Ghost 15 - Automatic shutdown after backup (Windows 7)

An older thread, "Ghost 15 -Automatic shutdown after backup" explains how to set use the post-backup command settings to run a script to shutdown the computer.  However, in WIndows 7 (64 bit), special privileges are required to shutdown the computer that do NOT seem to be present when the post-backup command file is executed.  Therefore, the computer does NOT shutdown after backup and stays on all night.

 

 

In my case, I run a file called C:\CommandFiles\PowerOff.cmd, which is based on a popular shutdown utility copied from the internet.  The guts of that command file includes a line:

 

start /i shutdown -s -m \\%computername% -t 300 -c "Type SHUTDOWN -A on a command line to abort the shutdown."

 

If you run the command file, it works as intended and shutdown the computer safely.

 

The command file also writes to a log file.  Just before the above  command line, I have a line that writes exactly that command to the log file.  Sure enough, the command is written to the log file after the GHOST 15 backup jobs completes, but the system does NOT shutdown.

 

The issue is on a laptop that is a member of a domain.  I suspect that the problem has to do with elevated privileges and that there is no option for GHOST to run the specified command file using elevated privileges.

 

How can I get the shutdown command to work from a command file launched by GHOST after a backup job on a Windows 7 (64 bit, domain member) computer  ?
