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!

Thanks a bunch for this.

Connect and share knowledge within a single location that is structured and easy to search. I have a web application hostname: service. I have created a keytab file in AD that contains a shared secret that should be enough to authenticate Kerberos tickets that are sent by the client browsers using the web application. My question is, is service host service. The service never needs to talk to the KDC. It needs a keytab generated by the KDC , but that you can copy over any way you want. They never have to talk to each other.

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 :.

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. If any such errors exist, there might be errors associated with the Kerberos protocol as well. Failure audits on the target server's Security event log might show that the Kerberos protocol was being used when a logon failure occurred. Before you inspect the Kerberos protocol, make sure that the following services or conditions are functioning properly:. If you've examined all these conditions and are still having authentication problems or Kerberos errors, you need to look further for a solution. The problems can be caused by how the Kerberos protocol is configured or by how other technologies that work with the Kerberos protocol are configured.

Check whether the service can use RC4 encryption or AES encryption, or check whether the vendor has an authentication alternative that has stronger cryptography. Depending on the scenario, you may have to set this policy at the domain level to apply the DES encryption type to all clients that are running Windows 7 or Windows Server R2. In this situation, the criteria 1 is satisfied by RC4 encryption, and the criteria 2 is satisfied by DES encryption. Send feedback to Microsoft so we can help.

Just to be clear, you experienced this issue right after you raised the domain functional level to ? Hi, I just had the exact same issue happen… this article saved me alot of grief. Maybe, but I highly doubt it. No jargon. Or, you may have to set this policy at the organizational unit OU of the domain controller for the domain controllers that are running Windows Server R2.
