Sometimes Microsoft messages are great, most of the times they are not, but they are getting better on it. When you get the following strange message:
your only option is to click “OK” and you get a second selfexplaining message:
Your only option will be clicking “End Now” and nothing happens and the login will not be succesful.
The cause is a blank in de “Logon Script” field within the users profile in Active Directory Users and Computers. This post shared with you all just to save you time 🙂
