Quite frequently all PCs in our office have to be restarted for various updates, configuration changes etc. We also have a policy of all PCs being turned off overnight and have become a little draconian in enforcing this - the electricity bills are huge otherwise!
A local or remote shut down or restart can be triggered using the command line.
shutdown [-i -l -s -r -a] [-f] [-m \\computername] [-t xx] [-c "comment"] [-d up:xx:yy]
No args Display this message (same as -?)
-i Display GUI interface, must be the first option
-l Log off (cannot be used with -m option)
-s Shutdown the computer
-r Shutdown and restart the computer
-a Abort a system shutdown
-m \\computername Remote computer to shutdown/restart/abort
-t xx Set timeout for shutdown to xx seconds
-c "comment" Shutdown comment (maximum of 127 characters)
-f Forces running applications to close without warning
-d [u] [p]:xx:yy The reason code for the shutdown
u is the user code
p is a planned shutdown code
xx is the major reason code (positive integer less than 256)
yy is the minor reason code (positive integer less than 65536)
You will need to be an administrator or have admin rights to remotely shut down or restart another PC. Whilst this can be useful technique only grant admin rights to those who really need them otherwise anyone in the office could start restart other workstations!!!
