hyper V 2012 VM could not initialize machine remoting system. element not found. could not find a usable certificate. element not found

hi,

I faced a similar issue with hyper V 2012.

https://social.technet.microsoft.com/Forums/en-US/a5164c6b-3fcd-4e43-94a8-06d54ff02e00/error-element-not-found-0x80070490?forum=windowsserver2008r2virtualization

VM could not initialize machine remoting system. element not found.

could not find a usable certificate. element not found.

1. Host has been rebooted.

2. Hyper Virtual Machine Management service has been restarted 

3. The certificate under vmms/personal has been removed and auto regenerated according to https://jamesosw.wordpress.com/2013/06/07/hyper-v-could-not-find-a-usable-certificate/

My VMs are still not able to start. Anyone faced similar problem before and resolve it successfully?

Thanks.
