$Username = "user"

$Password = "Password"

$servers = get-content "c:\temp\servers.txt"

$sb = {c:\temp\PsExec.exe -h \\$server -u $Username -p $password cmd.exe /c "echo . 
| Powershell.exe -executionpolicy bypass -file c:\script.ps1" > "$env:userprofile\Desktop\output.txt"} 

foreach($server in $servers)
{
    start-job -ScriptBlock $sb
}

this code works fine if i remove start-job, but executes one after the other, which takes lot of time.

I cannot use PSsession or invoke-command, since it is restricted in our environment.

This code never exits. It stops at this position:

 + CategoryInfo          : NotSpecified: (:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError
