My Server 2008 R2 Hyper-V host box started having problems. (and no, I didnt change anything on the server) The Hyper-V guest machines launch just fine. And I can connect to the guest machines via RDP from my laptop.
But if I try to right click connect from the Hyper-V host machine, it does nothing. No pop ups, no errors, nothing.
Same thing if I try to launch MSTSC.EXE. it does nothing. No pop ups, no errors, nothing. Doesn't even get to the screen that asks for the IP or host name.
Also, when I try to rt click the VM guest machine & select SETTINGS, it does nothing. No pop ups, no errors, nothing.
So the VM guest machines run fine. But something is wacked on the VM host box.
I've rebooted it, checked the event log, tried to re-register mstsc, deleted old un-used VHDs, etc.
