I needed to remotely reboot some servers in batches. Here is some quick code to reboot the servers. The script will issue the first reboot using the server names in the first .txt file. it will then pause and display a popup, wait 8 minutes and then fire off the second .txt file. This repeats until the end. You will need to change “Domain\account” to your domain and an account that has admin rights. Also note, that Powershell does not have a pause function like cmd.exe does. The pause function was created after finding some examples from around the web. Enjoy!
$Cred = Get-Credential -credential Domain\account
$servgroup = “”
Function Pause ($Message = “Press any key to continue . . . “) {
If ($psISE) {
# The “ReadKey” functionality is not supported in Windows PowerShell ISE.
$alert = $servgroup + “Server Group Rebooting. Waiting 8 Minutes.”
$Shell = New-Object -ComObject “WScript.Shell”
$Button = $Shell.Popup($alert,480, “Servers Reboot, Script Paused”, 64)
Return
}
Write-Host -NoNewline $Message
$Ignore =
