Microsoft Hyper-V Support

Edit the session and go to the Information tab. You need to set the checkbox to show it is a Hyper-V server.

HI,




the checkbox is enabled - without this, the HYPER-V column is inactive.

But no server appears...?!

I just poked around for a minute and see that I can recreate the same issue. My few remaining 2008 Hyper-V servers work but my 2008 R2 servers do not show anything, which I see is the same OS you're using too.

Hi,
Could you verify if you have the remote WMI access rights?

In my environment Windows firewall is disabled. I can also use Hyper-V manager from my workstation.

Could please try the following:

On the Hyper-V tab click the refresh icon. Open the application logs (Help->View Application Log...).

What do you see? Anything along the lines of "System.UnauthorizedAccessException: Access is denied." This may indicate wrong username, password or domain. Please double check the sessions's "Logon settings" credentials and modify the values as required.

Could you please send us the application log for analysis.

Thanks

It spams this:

Perfect thanks, we are looking into it. I may send you a small test application to help with the debugging.

More information to follow.

Thanks

@Liquidmantis

Could you try this version?

@salfer

I think that you don't have the access rights or the firewall block the WMI (RPC server unavailable)
http://social.technet.microsoft.com/Forums/en-US/virtualmachingmgrhyperv/thread/404551f5-657b-48be-8838-23e38dfd6269/

Works like a champ!

Your Fix works for me too, but only in LAN! If i connect to our Network with PPTP VPN (Firewalls on both Sides disabled), the same error?

I don't think that the RPC call are supported. Could you verify with the default Microsoft Hyper-V console?

Hi,
I've found this link that might help:

And maybe this

okay thanks - i research the problem!
And your fix (2008r2) 7.0.2.0.a - is this permanently so, or release a new version officaly?

Hi,
I already have uploaded the fix in the version 7.0.2.0 if you download it again.

Running 7.03. I've checked the boxes for the sessions for my Hyper-V servers. No firewalls between client and Hyper-V servers. I'm still not getting anything. I'm getting the:
[3/16/2012 1:26 PM]ERROR System.UnauthorizedAccessException: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo)

at Devolutions.RemoteDesktopManager.Managers.ThreadManager.<>c__DisplayClass15.<Execute>b__14(Object param0)

I have the session configured (on the "Connection" tab) for a credential repository, and if I open the session, I'm connected as expected. Just the Hyper-V window is empty. Am I missing a setting elsewhere? I don't see a "Logon Settings" option anywhere.

To see the logon setting, you need to enter it in the session Tool tab page.

Ah - ok. Same results, whether I use a credential repository, custom credentials, prompt for credentials, etc.

Are you sure that you have the admin rights for this machine? Does it work with the Microsoft Hyper-V console?

Yes. The credential repository I'm using is an admin on the machine (actually, is a domain admin), and is the same cred. repository I use to connect via RDP.

Could you try the Microsoft Hyper-V tools?

Not sure I understand the request. When I RDP into the Hyper-V server, I can use Hyper-V Manager without issue.

I mean, run Hyper-V Manager from your local machine without the RDP connection.

If I run it as another user, specify admin creds for the Hyper-V box, it works fine.
