Hyper-v Host Lost Network adapter information

One of our hyper-v server suddenly lost all network adapter information (physical as well as virtual adapter).

I suspect this could be caused by SCVMM since we have some network connection issue, and this could be created by some uncompleted job (this hyper-v host uses logical switch).

Is there anyway I can fix this Hyper-v host other than reinstall it?

Thanks,
