One morning one of our consultants logged into one of our clients server to setup a local user on a Win7 VM that we have setup by Hyper-V. He noticed that all of our other Virtual Servers we all offline. He had to reassign the RAM and then switch them back on again.
I have viewed all the event logs and found nothing that indicates they were shut off or that anyone had shut them off. Has anyone else encountered this phenomenon or could point me in the direction as to check why they these VS shut off by themselves?
