I'm currently tearing my hair out over an inability to connect to a Hyper-V VM on a Windows 2008 R2 Server.
One of the straws I'm considering clutching at is a complete removal of the Hyper-V role, and then adding it back in again.
Is there anything I should consider before trying that? I don't have physical access to the box, so I'm somewhat nervous of doing anything that could mess up the host OS.
Depending on how the networks are set up (you hopefully dont share hyper-v and management interfaces on one physical nic) you may loose network configuration... becasue the network configuration is on the virtual network card that your host uses, then after removal it uses the configuratin on the physical card.. which may be wrong.
That said - how can you not have physical access to the box? Who puts a box into a data center these days without spending the 70 or so euro for an IPMI / KVM controller card? Last time I had to reinstall a server I even remotely configured the bios level RAID controller using the nice little IPMI daughter card.
