You have a Hyper-V Server 2012 host (which means no GUI tools on the host itself) and no domain controllers online or available (which means no domain authentication). How exactly do you manage the host (and the VMs on it) from a remote Windows 8 computer?<\/p>\n\n\n\n
The first step is to run Hyper-V manager with a local account whose name and password match an administrative account on the host itself. Once you do that, however, you\u2019re likely to be able to connect to the host and manage the Hyper-V settings and Virtual Switches. In the list of Virtual Machines, though, you\u2019ll probably see an error:<\/p>\n\n\n\n
Access denied. Unable to establish communication between <Hyper-V Server> and <Hyper-V Manager Client>.<\/p>\n\n\n\n
It\u2019s not very clear, but it\u2019s not the Hyper-V host denying access exactly, it\u2019s a DCOM service that can\u2019t authenticate remotely.<\/p>\n\n\n\n
Here\u2019s the fix:<\/p>\n\n\n\n
Run %windir%System32dcomcnfg.exe as administrator.<\/p>\n\n\n\n
Expand \u201cComponent Services\u201d and \u201cComputers\u201d<\/p>\n\n\n\n
Right-click \u201cMy Computer\u201d and choose Properties.<\/p>\n\n\n\n
Select the \u201cCOM Security\u201d tab.<\/p>\n\n\n\n
Under \u201cAccess Permissions\u201d click \u201cEdit Limits\u201d<\/p>\n\n\n\n
Select \u201cANONYMOUS LOGON\u201d and check \u201cAllow\u201d for \u201cRemote Access\u201d<\/p>\n\n\n\n
Select \u201cALL APPLICATION PACKAGES\u201d and check \u201cAllow\u201d for \u201cRemote Access\u201d<\/p>\n\n\n\n
Click \u201cOK\u201d all the way out, and open Hyper-V Manager again.<\/p>\n\n\n\n
This time, you should see your VMs.<\/p>\n","protected":false},"excerpt":{"rendered":"
