Customer requested to force active directory accounts to expire on midnight or in the night and not during the day. So I’ve created following script to do so:

$UserList = Get-ADUser -Filter * -SearchBase "OU=USERS,DC=domain,DC=local" -Properties "DisplayName", "PasswordLastSet"
$Today = (Get-Date)
$MaxPasswdAge = (Get-ADDefaultDomainPasswordPolicy).MaxPasswordAge

ForEach ($User in $UserList)
   {
   $ExpireDate = ($User.PasswordLastSet) + $MaxPasswdAge
   $DaysToExpire = (New-TimeSpan -Start $Today -End $ExpireDate).Days
   If ($DaysToExpire -eq 1)
      {
      Set-ADUser -Identity $User -ChangePasswordAtLogon $true
      }
   }

#EOF

This script runs everyday at 23:55.

I found couple examples how to change pwdLastSet attribute on AD user’s object, but I don’t like that. I think this is cleared way to do so.

Have a nice day,

One of our customer migrated his whole IT infrastructure into another datacenter. We powered off virtual machines at production site and powered on cloned versions of virtual machines. Domain Controllers were up all the time. Only member servers’ clones moved into another datacenter. They’ve ran for three days in another datacenter. Active Directory domain was up all the time. After tests we deleted clones in another datacenter and powered on virtual server in primary datacenter – their friday’s copies. And now we had problems on couple of servers.
