Hi all, I have the start of a script which I want to run, parse a text file full of server names and record the PS version to a text file. Here is the script so far:

$computers=get-content c:\work\temp\serverlist.txt

foreach($computer in $computers)

{

invoke-command -computername $computer -scriptblock{$version=(Get-Command powershell).FileVersionInfo.FileVersion }

$result=new-object psobject

$result|Add-Member -MemberType NoteProperty -Name ComputerName -Value $computer

$result |Add-Member -MemberType NoteProperty -Name Version -Value $version

$result|out-file c:\work\temp\result.txt -append

}



But I get the error of:
Invoke-Command : Cannot validate argument on parameter 'ComputerName'. The argument is null or empty. Provide an argument that is
not null or empty, and then try the command again.

Can anyone teak this so it works for me please?
Thank you
Jason
