Service Restart Script for Non Admin Users

[spudw2k]

This information isn't strictly related to AutoIt--in fact the script was the easiest part--but I just finished an exercise that I hadn't had to do before but others may find useful so I wanted to share my findings and results.

At my place of work we have a "Desktop Admin" group which has admin privs on desktops (who da thunk) but not servers.  Our print server has daily hangups and our resolution is to restart the print spooler service.  We have a 24hr support model and only Desktop Admins are filling the night shifts.  If the print server or queue gets hung, they are were not able to restart the service.  We are unable to grant them login or admin privs on the server so I tried another route.

I learned that a Discrentionary Access Control List (DACL) can be applied to individual services. In addition to the Print Spooler service, at least status permission needed to be granted to the Service Control Manager service (scmanager).

I followed the following links for instructions to grant permissions to the SID of the Desktop Admin group.

Here is the simple script I put together for the Desktop Admins to run in order to restart the service.
