I am having some issues with a server 2019 hosting exchange server 2019. The issue is logging into the 2019 server and should have nothing to do with the exchanges themselves since we can still manage them using ECP, and they seem to be working fine.
I am hoping someone here can help. Last Friday, we did our weekly updates on the exchange servers. Once completed, the servers rebooted, and now we cannot log onto them. We have tried all kinds of troubleshooting, and we cannot explain why this has happened. However, when we select alt+ctrl+del and put in our username and password, it goes back to the lock screen once we hit enter. It will not let us log into the systems at all. We have backed all updates and checked to ensure group policies would do this. We have found nothing.
Has anyone seen this before or maybe know how to fix this issue. I can find nothing online to help. Thanks
