googling around issue points memory hw problems in computer being hyperv system many other vm's active don't see how it.  the vm in question server 2008r2 in "terminal server" mode, patched.  nothing of note in event logs , nothing (other updates last month) done on server lately.

any ideas on how proceed track down?  thanks.

bad physical ram possibility.

hyper-v carves out chunk of physical ram each vm on boot.  if vms rebooted vm have hit section of ram.

if dynamic memory @ play vms move onto , off it.  if not using dynamic memory vm given allocation contains bad blocks.

otherwise, expect vms experience storage issue, not one.
