Virtual Machine Cannot Mount ISO on System Center Virtual Machine Manager 2012 R2

A few days ago a user report to me that he cannot mounts ISO image to virtual machines on SCVMM 2012 R2. The error message is the following:

Error (2912)

An internal error has occurred trying to contact the dcahyv01.amat.com server: NO_PARAM: NO_PARAM.

 

WinRM: URL: [http://hyper01.contoso.com:5985], Verb: [INVOKE], Method: [GetError], Resource: [http://schemas.microsoft.com/wbem/wsman/1/wmi/root/microsoft/bits/BitsClientJob?JobId={89EC51A2-633C-4E06-8B09-3A84146830B5}]

The reason is the communication between SCVMM and Hyper-V servers are blocked due to certification on SCVMM application is expired. The default expiry date of SCVMM certification is 1/1/2019. The issue got fixed after renewing certificates in System Center 2012 R2 Virtual Machine Manager.
