Restart machine using powershell script - powershell

Question

I am running the below code but the restart is not working. My intention was to run restart command parallelly on all remote machines at once.
$YourFile = gc "machinelst.txt"
$username = "user1"
$password = "pass1"
$secpw = ConvertTo-SecureString $password -AsPlainText -Force
$cred = New-Object Management.Automation.PSCredential ($username, $secpw)
foreach ($computer in $YourFile)
{
Invoke-Command -ComputerName $computer -credential $cred -ErrorAction Stop -ScriptBlock { Restart-Computer -ComputerName $computer -Force } -AsJob
}

Answer 1

That looks like its the output from Get-Job - could you try Receive-Job $id (Receive-Job 80).
Should give you the actual exception.

Answer 2

This likely runs in parallel just like invoke-command does with an array of computernames:
restart-computer computer01,computer02,computer03,computer04,computer05
Or this. It takes a couple minutes for the winrm service to come back, but they all seem to reboot at the same time.
$c = get-credential
$list = 1..10 | % tostring computer00
restart-computer $list -wait -protocol wsman -cr $c

Answer 3

try this (you will can add -asjob if it's work) :
$username = "yourdomain\user1"
$password = ConvertTo-SecureString "pass1" -AsPlainText -Force
$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $password
get-content "machinelst.txt" | %{
Restart-Computer -ComputerName $_ -Authentication default -Credential $cred
}
if you want use job, you can do it :
$listjob=#()
get-content "machinelst.txt" | %{
$listjob+=Restart-Computer -ComputerName $_ -Authentication default -Credential $cred -AsJob
}
$listjob | Wait-Job -Timeout 30
$listjob | %{
if ($_.State -eq 'Failed' )
{
Receive-Job -Job $_ -Keep
}
}
