Hi  Readers,

Our team has to shutdown / Reboot a lot of servers due to some datacenter activities but unfortunately no one was available due to holiday season. So as I luv PowerShell,  the idea was to automate the process & send notification ones the action is completed.

You can download the solution from TechNet :-

http://gallery.technet.microsoft.com/Monitor-Shutdown-Restart-19ec13da

Don’t forget to rate.

Change the variables defined at the top of the script:

Enter the server names in the servers.txt file.

#####Declare variables & add logging###################

$email1 = “VikasSukhija@lab.com”
$from = “don_not_reply@lab.com”
$smtpserver =”smtp.lab.com”

$action = “Shutdown” ###########value should be Restart or Shutdown##############

————————————————————————————————————————————————————-

Here is the shell script:-
