Getting this for almost all my users on my exchange 2010 box along with a terminal services server and a team foundation server. It just started today after rebooting domain controllers last night, one domain controller didn't come up right away due to an F1 prompt but was brought up about 2 hours later.
All my exchange users are getting the prompt for their username/password but email is still working.
I'm under a lot of pressure to get this resolved and can't find the resolution.
