Ensure that the Windows Remote Management (WinRM) service and the VMM agent are installed and running and that a firewall is not blocking HTTP/HTTPS traffic. Ensure that VMM server is able to communicate with %ServerName; over WinRM by successfully running the following command:

 winrm id –r:%ServerName;

This problem can also be caused by a Windows Management Instrumentation (WMI) service crash. If the server is running Windows Server 2008 R2, ensure that KB 982293 (http://support.microsoft.com/kb/982293) is installed on it.

If the error persists, restart %ServerName; and then try the operation again. /nRefer to http://support.microsoft.com/kb/2742275 for more details.
