Tuesday, May 15, 2012 3:44 PMTried to install the Hyper-V role, and on reboot I got 'hyper-v Object reference not set to an instance of an object'. At this point, I'm unable to manually create a VM in Hyper-V manager as I get an unexpected logon failure - I'm currently logged in as a Domain Admin. Any help would be much appreciated!

Have you tried to disable and then enable the Hyper-V role again to see whether you can resolve the issue.

Yes, we've tried that. We've also tried a fresh install of Server 8 and get the same issue.
Wednesday, May 16, 2012 12:52 PMModeratorWhen you did the fresh install, did you also delete the Computer Object for the Hyper-V server in AD and let the domain join create a fresh CO?

Did you use Windows 8 Consumer Preview or Windows Server “8” Beta?
