Hyper-V Manager–“Access denied. Unable to establish communication between…”

I manage several virtual machines running on Microsoft Hyper-V. To administrate them, I installed the “Remote Server Administration Tools for Windows 7”.  This included the “Hyper-V Manager”.

One issue that appears is when attempting to connect to a remote Hyper-V server, the “Hyper-V Manager” reports “Access denied. Unable to establish communication between…”. 


To resolve this problem, run “Component Services” manager and expand “Component Services – Computers – My Computer”. 


Right-click on “My Computer” and choose “Properties”.


Under “Access Permissions”, click “Edit Limits”.


Click “ANONYMOUS LOGON” and select “Allow” for “Remote Access”.

Now, simply re-launch the “Hyper-V Manager” and you will be able to connect to your remote Hyper-V servers.

    Thank you for this blogpost. I’m teaching myself hyper-v and this was one of the first results on Google for this error message.

    Many thanks for this…I still have some hair left!
    OK, now seriously…are you telling me that when setting up the Remote Hyper-V console, the installer can’t figure out thi stuff, like that I’m in a workgroup, and *at least* prompt me to complete certain? 3 hours of configuring firewalls and adding trusted hosts and registry settings is simply ridiculous…not all the world’s a Domain!

    Excellent! A simple solution to a confusing and misleading message.
    Thank you!

    Thanks for the help. Tho, it didn’t work at first. I needed to check the Internet Service COM checkbox to make it work. No need to close the console, just refresh and it worked.
