[How can I run a 'net start' from PHP via IIS]

Sometimes my mailserver craps out and I need to restart it.  Since RDP is blocked at my current company, I was hoping to simply make a button on a password protected webpage to start it.  This would be a simple button and no user config so as to reduce security risk (hopefully).

 

I need to do something like:

 

echo exec('net start abc');

 

This works if I use 'whoami' or 'hostname', but not with the 'net' command.

 

Also, the whoami shows the following:

 

nt authority\network service

 

This is using IIS/WIN2003
