Vmms.exe processes freeze on certain nodes in a Windows Server 2012-based Hyper-V failover cluster
Assume that you deploy a Windows Server 2012-based Hyper-V failover cluster that is based on a scale-out file server cluster. When a failover starts, the Vmms.exe process freezes on some of the failover cluster nodes. Therefore, several virtual machines are in the offline state.
This issue occurs because of a mismatch of the access tokens.
