My question is, is service host service.

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?

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.
