Finding a computer in the AD using #Powershell

So I need to search the AD today for computer objects to see if a description has been set.

$Domain = ([System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()).Name
$Dom  = “LDAP://DC=” + $Domain.Replace(“.”,”,DC=”)
$strComputer = “<computer2search4>”
$strFilter  = “(cn=$strComputer)”
$Root       = New-Object DirectoryServices.DirectoryEntry $Dom
$selector   = New-Object DirectoryServices.DirectorySearcher
$selector.PageSize    = 1000
$selector.Filter      = $strFilter
$selector.SearchRoot  = $root
$selector.SearchScope = “Subtree”
$Objs = $selector.findall()
$Objs.count

The results are in the variable $Objs
