We recently started to experience a problem with Zenworks. When our users used to login to AD, they would never seen the Zenworks login window. The only time they would see that previously is if they were not on the network when starting up their computer.

Now, everyone even if they are on the network gets the prompt for login to Zenworks. Typing in the AD password, which always worked before is no longer working. I've checked the ZCM server and all the services for Zenworks are running.

Any ideas?
