Powershell - List all servers in the domain and the OU

I have a script to list all the servers in our domain but I need it to output to a text file. Here is what I have but it is not working and hoping someone can help we out.

$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.Filter = '(OperatingSystem=Window*Server*)'
"Name","canonicalname","distinguishedname" | Foreach-Object {$null = $objSearcher.PropertiesToLoad.Add($_) }
$objSearcher.FindAll() | Select-Object @{n='Name';e={$_.properties['name']}},@{n='ParentOU';e={$_.properties['distinguishedname'] -replace '^[^,]+,'}} | ft -autosize | out-file c:\AllWindowsServerList.txt
