My exchange server (2013) is on a hyper-v machine. Both host and virtual machines are 2012 r2.
I upgradedthe ram chips from 32gb to 64gb and host machine booted up fine. Changed ram on virtual machine to 60gb and booted it up.
All seemed fine but then i noticed that there were some problems. Exchange never came back online and i cant rdp in to the server, i can only log in via host machine hyper-v session.
The server pings, and i can see services etc, but if i try to say open control panel then > windows firewall it will freeze. I cant get in to network options either.
I have now swapped back to the original ram and rebooted but still having the same issue.
need help with this ASAP as this is only exchange server in our domain so all emails are currently down.
I can get in to the event viewer but nothing seems to jump out either on host or virtual machine.
