PowerShell, Active Directory : Uncheck password does not expire
If you have lots of accounts that have passwords set to never expire this script will hunt them out and correct that for you
Import-Module ActiveDirectory
#Search for the users
$NonExpireUsers = get-aduser -filter * -SearchBase 'DC=domain,DC=co,DC=uk' -properties Name, PasswordNeverExpires | where {$_.passwordNeverExpires -eq "true" } | Select-Object SamAccountName,Name,Enabled
Foreach ($NonExpireUser in $NonExpireUsers)
{
($NonExpireUser.SamAccountName) | Set-ADUser -PasswordNeverExpires:$false
}
