Concurrent Powershell jobs not running command - multithreading

Question

Hey guys first time poster long time reader, I'm having a bit of trouble with my script at the moment and was hoping some would check it out and point out where I've gone wrong, it is as follows:
$Servers = gc "C:\ServerList.txt"
$SB = {
Start-Process {cmd (C:\psexec.exe \\$Server -u username -p password cmd /c "echo.| powershell C:\Autolog.ps1")
}
Foreach ($Server in $Servers)
{
Start-Job -ScriptBlock $SB
}
Essentially what I'm trying to get this script to do is for Every server in "Serverslist.txt" Start a PSEXEC which then initiates an Powershell script on said server
What i'm seeing is that the jobs start but my psexec isn't triggering on the servers and i know that line is good as i've completed isolation testing on that command and manually triggered it

Answer 1

This is likely way more complicated than it needs to be. I would run a scriptblock against that list of computers instead like so:
$cred = New-Object System.Management.Automation.PSCredential ("domain\username",(ConvertTo-SecureString 'password' -asplaintext -force))
foreach ($server in $servers) {
Invoke-Command -ComputerName $comp -ScriptBlock {. C:\Autolog.ps1} -Credential $cred
}

Your job doesn't know what $Server means because jobs run in their own process, and so don't access the parent process' variables. You have to pass the argument. Try this:
Start-Job -ScriptBlock $SB -ArgumentList $Server

Appreciate the help ended up nutting it out and getting it to do what want, the script is as follows:
$Servers = gc "C:\ServerList.txt"
Foreach ($Server in $Servers)
{
[String]$cmd = "& cmd (C:\psexec.exe \\$Server -u Username -p Password cmd /c C:\Autolog.bat)"
[ScriptBlock]$SB = [ScriptBlock]::Create($cmd)
Start-Job -ScriptBlock $SB -ArgumentList $Server
echo "Started Script on $Server"
}
I had to move some of the command out to a .bat because I don't have time to troubleshoot the issue but i'm essentially the C:\Autolog.bat contains "powershell.exe C:\Autolog.ps1" from the first script post
