Microsoft Powershell – Add Admin Users to Admin Groups based on csv-file

Release date: December 22nd 2022

Welcome to my Microsoft Tips & Tricks section. I recently experienced a complete hardware crash in my old lab, and had to do a complete rebuild. Although this was sad, it gave me the opportunity to do it by scripting this time. This involved recreating the admin users and groups, and adding the admin users to the correct admin group, as shown below.

The script below uses a csv file with the following data:

  • User
  • Group

Next, using the script below, I easily added the admin users to their corresponding admin groups. NOTE: The user I ran this script with had Domain Admin permissions, otherwise this wouldn’t have worked.

$server = "fqdn ad controller"
Import-Module ActiveDirectory
$file = Import-Csv "<Path to csv fil>.csv" -Delimiter ";"

Write-Host *** Input file contains $file.Count lines.
foreach ($row in $file) {
  Write-Host $row.user will be processed -NoNewline
  $user = $row.User
  $grp = $row.Group
  Write-Host ... $user ... $grp -NoNewline

  Add-ADGroupMember -server $server -identity $grp -Members $user -Confirm:$false

  Write-Host ... done.
write-host *** All selectable records processed

Now that I had created the Admin Users and Groups, I could proceed with creating vm’s and installing the servers in my domain, which I also did by using a script, detailed here: VMware PowerCLI – Deploy and setup multiple servers

Big thanks to: Peter Buijsman’s: Quickly add users to groups from CSV via Powershell
