Replace computername with the name or IP address of the remote computer you want to restart.

You may encounter an error if you don’t have permission to connect to the remote computer. In this case, you will need to use a PowerShell credential object to authenticate your login. You can do this by using the following command:

#Get credentials to connect
$cred = Get-Credential

#Restart remote computer
Restart-Computer -ComputerName <Computer-Name> -Credential $Creds -Force

This command will prompt you to enter your credentials. Once done, the Restart-Computer command initiates the restart process.

Restart-Computer -ComputerName "Server1","Server2","Server3" -Force

This restarts the computers Server1, Server2, and Server3 without confirmation prompts.
