Connect and share knowledge within a single location that is structured and easy to search, kdc 2008. I have a web application hostname: service. I have created a keytab file in AD that contains a shared secret that should be kdc 2008 to authenticate Kerberos tickets that are sent by the client browsers using the web application.

This article describes various scenarios in which you may receive the following events in the Application, Security, and System logs because DES encryption is disabled:. For detailed information, see the "Symptoms," "Cause," and "Workaround" sections of this article. In any of these scenarios, you may receive the following events in the Application, Security, and System logs together with the Microsoft-Windows-Kerberos-Key-Distribution-Center source:. By default, the security settings for DES encryption for Kerberos are disabled on the following computers:. Services that are configured for only DES encryption fail unless the following conditions are true:. We strongly recommend that you check whether DES encryption is still required in the environment or check whether specific services require only DES encryption.

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.

To be safe, we restarted all the domain controllers since we were in a maintenance window. Hotfix is required for the Windows Server R2-based domain controllers to correctly handle encryption type information that is replicated from the domain controllers that are running Kdc 2008 Server Add a comment, kdc 2008.

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. To determine whether a problem is occurring with Kerberos authentication, check the System event log for errors from any services such as Kerberos, kdc, LsaSrv, or Netlogon on the client, target server, or domain controller that provide authentication.

Active Directory Security. Nov 10 It is a domain account so that all writable Domain Controllers know the account password in order to decrypt Kerberos tickets for validation. Microsoft does not recommend moving this account to another OU. From Microsoft TechNet :. This account cannot be deleted, and the account name cannot be changed. Windows Server Kerberos authentication is achieved by the use of a special Kerberos ticket-granting ticket TGT enciphered with a symmetric key. This key is derived from the password of the server or service to which access is requested. It attempts to decrypt with the current password and if that fails, it attempts again with the previous one assuming it has it.
