We are running Zenworks 10.1.2. and we are on Microsoft Exchange 2007. Whenever our employees login to the domain at work, then never see the Zenworks login screen as it logs them into Zenworks with no issues. Obviously when they are remote and not VPN, when they startup they get the login window, but can hit cancel and still make it into Windows.

Recently, people in the office started seeing the login window for Zenworks, and what worked previously is that they would enter their AD password and that would work. Now we get an error something about a certificate. No matter what it no longer accepts the AD login password.

I've done some research here, but so far I've found nothing. Any help is appreciated.
