Hi
We're running VMM 2012 R2 to monitor a Hyper-V cluster running on 4 Windows Server 2008 R2 hosts. VMM service is installed on a Windows 2012 R2 server that is also a domain controller.
If I use the VMM GUI to put a host into maintenance mode, or when I reboot a host that is in maintenance mode, vmmservice.exe often crashes with the following logged in the eventlog:
Application: vmmservice.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.InvalidCastException
