You can try workarounds in below article

http://support.microsoft.com/kb/2742246

However I fill that restarting VMM services on SCVMM server and VMM Agent service on Hyper-V host should resolve your problem

hyper-V is having 2012 R2 core datacenter version with GUI and SCVMM is 2012 r2. all host and SCVMM is in domain and there is no domain policy applied to the host and SCVMM ( we created another OU for these machines and no policy set on this OU).

Firewall also allowed all incoming pkts.

WinRM and WMI working fine (checked using the commands as well)

Rebooted all host servers and SCVMM with no luck..



Mahesh,

I already tried these things with no luck. :-(

I had the same problem but it ended up being related to a GPO that was enabling WinRM.

Has this error just occurred or has anything else happened?
Can you carry out any task against a host?
Is DNS and time OK?

Can you tell me which GPO you are talking about.. coz as per wintel team there is no GPO applied to this OU ( I personally checked on server)

It was working fine but after applying some GPO we got issue in live migration so moved all host and SCVMM app and DBS server to this OU where no default policy applied, live migration issue fixed but this host not responding issue starts.

DNS / date / time is OK on all servers.

Policies\Administrative Templates\Windows Components\Windows Remote Management (WinRM)\WinRM Service\

Allow Remote Server management through WinRM - Enabled
Allow automatic configuration of listeners - Enabled

Once I removed the GPO, did a gpupdate /force and rebooted everything was fine.

I tried with these settings with no luck.

Also I got the below warning multiple time in a day.
The Virtual Machine Manager management server could not copy a required Hyper-V authorization file to CLUSTER-NAME.domain.com

Are both the VMM computer-account and the SCVMM service account members of the administrators group on the Hyper-V servers?

Can you remove the host from VMM and then re-add? That should reset the authorisation file.

Depending on your setup you could move the VMs off the host using the Failover Cluster manager. Then remove and re-add.
