Exchange 2010 Console–WinRM or Kerberos errors

We’ve seen this quite a bit on Exchange 2010 machines where the Exchange 2010 console will just hang when you try to access it.  After a period of time you might get a Kerberos or a WinRM error being displayed.  This seems to be a fairly common problem as there is a great deal of whining about the problem out there on the Web.  We have found that disabling the local antivirus client (in our case Trend WFBS7 but others seem to have similar issues) will allow you to access the console without any further problems.  Just remember to restart the antivirus when you have completed your Exchange management task.

Also, note that there is a nice tool available to troubleshoot these types of errors available from  but be aware that the tool does NOT identify errors caused by antivirus clients.  If disabling antivirus does not gain you access to the console then follow through with the tool and the tips offered on the post.
