Recently I have had problems connecting to the console on a number of R2 Hyper-v guest virtual machines. Use the Ping or PathPing command-line tools to test network connectivity to local domain controllers. The Exchange server was able to ping and resolve all DNS names correctly and the problem went away on restarting only to re-occur in 24 hours or so. I restarted the Box, only to have the problem come back in about 10 hours. Your solution worked great! I noticed you had just posted this entry, is your system still functional? Just to be clear, you experienced this issue right after you raised the domain functional level to ? We experienced the same issue a few days ago when the Domain functional level was upgraded to r2. We had issues with a reporting software we use that uses Kerberos authentication as well. I know this does something to the krbtgt service account…and our domain had years ago. We had a few issues with Mac computers occasionally failing to authenticate which was also resolved when the KDC service was restarted. For me, the issue occured literaly within about 30 minutes of changing the Functional Level. It only affected one of our Exchange servers, the one with Mailboxes on it. I have not had the issue re-occur once the KDC services were restarted.

Or, you may have to set this policy at the organizational unit OU of the domain controller for kdc 2008 domain controllers that are running Windows Server R2. We had a few issues with Mac computers occasionally failing to authenticate which was also resolved when the KDC service was restarted. In this situation, the criteria 1 is satisfied by RC4 encryption, kdc 2008, and the criteria 2 is satisfied by DES encryption.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. This topic for the IT professional describes new capabilities and improvements to Windows implementation of the Kerberos authentication protocol in Windows Server and Windows 8. The Windows Server operating systems implement the Kerberos version 5 authentication protocol and extensions for public key and password-based authentication. Initial user authentication is integrated with the Winlogon service single sign-on architecture. AD DS is required for default Kerberos implementations within the domain or forest. In Windows Server and Windows 8, Kerberos authentication can be leveraged to address lack of connectivity to the domain controller from outside the corporate firewall. To do so, it proxies Kerberos authentication and password change messages for users who are requesting domain access through DirectAccess or Remote Desktop Services. As sign-in scenarios become more complex, the amount of authorization information that is contained in the authentication messages increases, which in some cases leads to an authentication failure. In Windows Server and Windows 8, improvements have been made to accommodate this increase.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. This guide provides you with the fundamental concepts used when troubleshooting Kerberos authentication issues. A Kerberos-related error is a symptom of another service failing. The Kerberos protocol relies on many services that must be available and functioning properly for any authentication to take place.
