function rebootSystem {
param(
[Parameter(Mandatory)]$Computer,
[Parameter(Mandatory)]$userCreds
)
try {
Restart-Computer -Credential $userCreds -ComputerName $Computer -Wait -Force -ErrorAction Stop
$props = [ordered]@{
name = $Computer
result = "Success"
}
}
catch {
$props = [ordered]@{
name = $Computer
result = "Failed $($_.exception.message)"
}
}
return (new-object psobject -property $props)
}
$CWD = Split-Path -parent $MyInvocation.MyCommand.Definition #Current Dir of script
$Computers = Get-Content "$CWD\servers.txt"
$domainCreds = Get-Credential
foreach ($Computer in $Computers) {
Write-Output "Starting reboot on $Computer"
start-job -ScriptBlock ${function:rebootSystem} -ArgumentList $Computer,$domainCreds | Out-Null
}
while (get-job | where State -eq 'Running'){
$jobcount = (get-job | where State -eq 'Running').count
Write-Output "We are still waiting on $jobcount reboots, sleeping for 10 seconds and check again"
Start-Sleep -Seconds 10
}
$logfile = "$CWD\reboot-$(get-date -Format 'yy-MM-dd-hh-mm-ss').log"
$endresult = get-job | Receive-Job -Force -Wait
get-job | Remove-Job
$endresult | Select name, result | ogv
foreach ($result in $endresult){
"$($result.name), $($result.result)" | Out-File $logfile -Append
}
#we can all sort of things with this output, for example we can filter out the failed ones or just write them all to a log file.
