Get Certificate from remote computers

If you need to get all certificates, from a list of remote computers, you can use this script:

$Servers = "kennethdalbjerg-dc01",
           "kennethdalbjerg-dc02",
           "kennethdalbjerg-exch01",
           "kennethdalbjerg-fs01"
 
  $Results = @()
  $Results = Invoke-Command -cn $Servers {
          $Certs = @{} | Select Certificate,Expired
          $Cert = Get-ChildItem Cert:\LocalMachine\My
          If($Cert){
              $Certs.Certificate = $Cert.subject
              $Certs.Expired = $Cert.NotAfter
          }
          Else{
              $Certs.Certificate = " - "
              $Certs.Expired = " - "
          }
          $Certs
  } | Select-Object @{n='ServerName';e={$_.pscomputername}},Certificate,Expired
 
  #Display results in console
  $Results | Sort-Object Expired -Descending
 
  #Save results to CSV file
  $Results | Sort-Object Expired -Descending | Export-Csv -Path C:\users\$env:username\desktop\cert_results.csv -NoTypeInformation -Force
 
  #Open results in new window
  $Results | Sort-Object Expired -Descending | Out-GridView -Title "Final results"
