How to restart specified service via task scheduler in windows sever 2008

Try using this:

Get-Service -ComputerName SRV-s3011 -Name MSExchangeTransport | Restart-Service -force

Also make sure the service is running with an account that has permissions to restart that service, Set it to run if user is logged in or not, and make sure you input the path to the script even though it is optional.

Here is a guide to set Powershell scripts as scheduled tasks

I have to run remotely ... from sSRV-Task220  to SRV-s3011 , Di i need to just copy above  given command to .ps1 file

Yes, just copy the above command and be sure to go through the guide to make sure it starts correctly.

 It may not be running because of Execution Policy rules and credentials. Also, be sure to fill in the Start in (optional) field and input the path to the folder. I have noticed that sometimes, scripts do not run when the path is not defined.

Please check screen shot if it is correct.

that may work but you should only need to do

powershell.exe c:\bats\.......

You also may have to add "-ExecutionPolicy Bypass" if it does not run. Did you look through the guide?

how to pre-check this command/ps script , i do not want to run service now.

change the computer name to your computer and change the service name to spooler then run the scheduled task. Make sure it runs correctly then change it back.

Check on your computer that the print spooler service was restarted.

Get-Service -ComputerName ADA-3E145085S-L  is  working fine but 2nd path I am getting error.

Restart-Service : Service 'Print Spooler (Spooler)' cannot be stopped due to the following error: Cannot open Spooler service on computer 'ADA-3E145085S-L'.

You have to run the script with elevated privileges.

I am running with admin rights

in the scheduled task setup, did you select the box that says run with highest privileges? What account do you have set to run the task?

If you are trying to test the script by itself, you have to open powershell as admin by right clicking

yes , i opened the powershell as admin by right clicked

OK, does your account that you logged into the server with have Domain Admin privileges?

yes

To be clear, this is what you are pasting into an elevated powershell window

thanks
