After a power outage that powered off the domain controller, which came back online with no errors, I cannot connect to my two SQL servers. The attached is what shows when attempting to connect.
The error only shows when Authentication is set to Windows Authentication and from a client workstation. Locally on the server I can connect using Windows Authentication.
Here are the details of the event log on one of the servers, SQL 2008:
