SCVMM expired certificates

Certificates for SCVMM on our Hyper-V cluster have expired.  I have run through renewing the certificates and the SCVMM servers are now renewed but the Hyper-V hosts have not.  Currently SCVMM cannot talk to the hosts at all, just saying "Host Not Responding".

I cannot find any information on how to renew the Hyper-V Host certificates.  Any assistance would be appreciated
