2012 Server Hyper-V Network
1 - Virtual 2012 Domain Controller
1 - Virtual 2012 running Exchange
This morning the Exchange host did a crash reboot in the middle of the backup. After the server came back up, Outlook clients are constantly prompted to authenticate and it will not accept the users' password. If I enter the Domain Administrator credentials then Outlook will connect to Exchange and function. Outlook Web Access and Mobile Devices using Exchange ActiveSync are unaffected by this. I've dug through the Windows logs and IIS logs and I can't find anything that sheds a light on this.
