Part 2 - Hyper-V Remote Management: You do not have the required permission to complete this task. Contact the administrator of the authorization policy for the computer ‘COMPUTERNAME’

Update 14th Nov 2008. I've just released a script which does all this configuration in one or two command lines: HVRemote 

Quick links to the all parts in the series: 1, 2, 3, 4 and 5 

The second part of the extra-long blog post contains the steps necessary on the client machine. Part one concentrated on the server side configuration.

Step 5 (On the client)

Step 5 mirrors step 2 in the first part of this blog post, but on the client. Note also (again for convenience more than anything else), my Vista SP1 machine is actually itself a virtual machine running on the same physical machine as the server. You’ve got to love it when you can have a somewhat recursive technology ;)
 
Enable the firewall rules on the client for WMI (Windows Management Instrumentation). From an elevated command prompt, enter the following:

netsh advfirewall firewall set rule group="Windows Management Instrumentation (WMI)" new enable=yes

Make sure the command it successful and responds: Updated 8 rules(s). Ok.

wg27

If you now open “Windows Firewall with Advanced Security” from Control Panel/Administrative Tools on the start menu, you will notice eight rules, six inbound and two outbound have been enabled. (It helps to sort by Group)

wg28

wg29 

Step 6 (On the client)

This step creates a firewall exception for the Microsoft Management Console application (mmc.exe). From an elevated command prompt, enter the following:

Netsh firewall add allowedprogram program=%windir%\system32\mmc.exe name="Microsoft Management Console"

Make sure the command is successful and responds “Ok.”

wg30

You can verify that you succeeded in the above step by looking in the “other” Windows Firewall application. (No, I have no idea why there are two either….). Open "Network and Sharing Center" on the control panel, and click Windows firewall in the bottom left corner, then click "Allow a program through Windows Firewall" where you’ll see a new entry with the name “Microsoft Management Console”

wg31

wg32

wg33

Step 7 (On the client)

IMPORTANT!!!! You need to do this step in the following scenarios:

  • Client and server are both in a workgroup
  • Client is a workgroup and server is in a domain
  • Client is in a domain and server is in a workgroup
  • Both client and server are in domains, but there is NO TRUST between them.

You DO NOT NEED TO DO THIS STEP if the client and server are in either the same or trusted domains. Go to step 8.

WMI makes calls back from the server to the client. This is entirely expected (and is not Hyper-V specific). When a server is in a workgroup, the DCOM connection from the server back to the client is "anonymous". This step therefore grants the appropriate permission.

On the start menu box (yes, well spotted, I need to apply updates), type dcomcnfg and hit enter to open Component Services. If UAC is enabled, click allow when prompted or enter appropriate administrative credentials.

wg34 

Expand the tree down through Component Services\Computers\My Computer, select My Computer, right-click, choose properties and select the COM Security tab.

wg36

Click Edit Limits in the Access Permissions area (do not confuse with Edit Limits in the Launch and Activation Permissions area). Select “ANONYMOUS LOGON” from the list of users, and make sure Remote Access/Allow is checked in the permissions area. Your screen should look like below.

wg37
Click OK and OK again, and close Component Services.

Step 8 (Away from the keyboard)

Take a deep breath and pat yourself on the back. Now do that again. A third time if you like. Then double-check to make sure you followed the above steps and those in part one  to the letter.  You did remember the step about restarting the server, didn't you?

Step 9 (On the client)

Logon as the account you have granted permissions to (“john” in my walkthrough) on the client.

Start Hyper-V Manager from Administrative Tools on the Control Panel. Enter appropriate administrative credentials if UAC is enabled and the account is not an administrator on the client.

Click Connect to Server and enter the name of the remote machine.

Watch in awe as you get a screen like below. You can also see, it took me 2 hours, 24 minutes and 19 seconds to do this walk-through documenting it step-by-step. It should take you much less time!

wg39

Cheers,
John.

    Rob - there's a couple of things here. Make sure you cover the steps in part 5 which covers a domain joined client to a workgroup server. Similar to this, but a couple of nuances. However, what's most likely blocking this working is the external firewall you are describing. WMI/DCOM are not particularly "external firewall friendly" due to the number of ports you need to open, so I would not recommend the scenario you are trying to achieve. I'm not sure the exact list of ports you need for this - haven't tried it myself, but as I understand it the default ports are 135 49152-65535   2179 There's a couple of articles about this you may want to read: http://msdn2.microsoft.com/en-us/library/ms809327.aspx http://support.microsoft.com/kb/217351 If you're also behind a NAT router, I don't believe remote DCOM calls would work. I'm not sure of your exact topology, but I would look towards a TSGateway which you can remote Hyper-V manager through and use mouse (once the integration services are installed - I have an entry a short while ago describing how to use the keyboard to drive the installation of that without mouse), or use TS directly to the server and run Hyper-V Mnaager on the server (unless it is Server Core). Hope that helps. Thanks, John.

    Robr - I was thinking about this some more. With the caveat that I have never tried this, it may be possible to tunnel DCOM over HTTP using the RPC over HTTP proxy mechanism. When I get a chance, I'll build up a lab environment to see whether it's possible. There's some interesting information here: http://msdn2.microsoft.com/en-us/library/ms809302.aspx You will still need port 2179 for the VMConnect video RDP connection though. Thanks, John.

    Dave - in which case, you should get the same result as creating a new user by simply runing "hvremote /add:yourusername" on the server. You still need to verify the client settings though (mmc and anondcom) as this is a workgroup. It should work then :) I hope, anyway! Cheers, John.

    Hi Jonathan - Yes, I've seen reports of OneCare which (as I understand it - never have used it) has it's own firewall which blocks part of remote management. Let me see if I can get hold of a copy to install and see what the problem is to find the solution. Stay tuned... Thanks, John.

  • Anonymous
    January 01, 2003
    Dave - actually not quite true. You can /show the settings as an administrator from an unelevated command prompt on a Vista client, but not change the /mmc or /anondcom settings - you will hit permission denied. Similarly on the server, you cannot read the security permission for a WMI namespace unless you are elevated. I'm pretty sure this is related (for WMI) to UAC token filtering as described http://msdn.microsoft.com/en-us/library/aa826699(VS.85).aspx. However, in both client and server cases, this is really a question for those who developed the security model rather than for myself who's trying to manipulate it :) So nutshell.... you still need to be elevated on both client and server to do anything useful. Thanks, John.

    Dave - I'm not sure is the simple answer - I'll need to verify in my "test lab" which is all setup in my office at work (quicker than trying to set it up on my home servers) and run some network traces to work that out. Let me check tomorrow. If that is the case, as you seem to be saying, then I'll add that to HVRemote to report on in the /show and to have the ability to change in the next version.... That having been said, now you mention it, this does ring some distant bells. I'll have to have a dig through my archives in the office. Out of interest, did you deliberately change any of the firewall rules on the server before running the tool. When I was doing my testing, I used a vanilla install and only ran the tool for the configuration, so I never tried it with other combinations. Thanks, John.

    Dave - I should have made it a bit clearer in the post (and I can make a check in the code if I can work out how). You must run the script as an administrator from an elevated command prompt. Without elevation, or running it as a standard user will give exactly that error. It should work when elevated by any account that is a local administrator. Thanks, John.

    Dave - That's really odd if disabling the firewall on the SERVER makes connections start working. Can you try turning it back on again and creating a seperate user account - I'm assuming you're using "Administrator" here: On server net user <username> /add *, type the password. Do same on client and make sure the passwords are the same. Then run hvremote /add:username on server. If the client is workgroup, please also run hvremote /anondcom:grant. Also remember to run hvremote /mmc:enable on the client. Try that, when logged on as the new user. If that still fails, and also fails after a reboot, please can you re-post the hvremote /show on both the client AND the server. Thanks, John.

    re "I have Windows 2008 DataCenter Edition with the Hyper-V role installed. Do you have the standalone Hyper-V Server version that does not include additional roles (other than the Hyper..." question. Not sure I understand the question, but I've tried this on full and Hyper-V Server with no repro. Microsoft Hyper-V Server is not based on WinPE - it should have a black background with a default install, so not sure where green comes into this. Realistically, if you're still having problems here, please run hvremote /show /debug:verbose on the server and the client and let's see if there some other clue in there. Email link is at the top.

    January 01, 2003
    Scott - correct. I was being over cautious in saying reboot. Restarting the Hyper-V services which are dependent on winmgmt is sufficient - it was just easier to say "reboot". Obviously allowing anonymous callbacks has a security implication, but I don't know the specifics. The closest information I could find published was at http://technet2.microsoft.com/windowsserver/en/library/4c9a2873-2010-4dbb-b9dd-6a7d1e275f0f1033.mspx?mfr=true. However, please note that you do not need to enable anonymous callbacks if both machines are in trusted domains. This is something I keep meaning to add to the walkthrough, but haven't got  round to quite yet..... Thanks, John.

    Fabrice - it depends entirely on whether you are using "The Administrator" account, and whether you are are in a workgroup or domain. Generally, as "The administrator", you don't need any configuration on the server. See part 5 of the series for a scenario where you do need to use cmdkey for Hyper-V remote management. Thanks, John.

    I was pointed here after trying to connect and getting the error "Cannot connect to the RPC service, make sure your RPC service is running". I followed all the instructions, with the exception of the firewalls steps as Windows Firewall is disabled on both computers. My client PC is here at the office behind a firewall.  I log into a domain here at work from the PC, so it's not a workgroup config on the client side. The server is located remotely at a data center, no firewall in front of it, windows firewall disabled, and is a standalone server.  Because of this setup, I need to get this working so I can have mouse control of the remote VMs. Could my error be a firewall issue here at work related to RPC?  Thanks for all the work and well documented instructions.

    Thanks very much John, I'll take a look at some of your other suggestions.  I'm running some Linux VMs, so I'm not certain integration services (in the case of SLES 10 which does have integration services installed, but I also have a Fedora VM) will solve all my mouse related issues.  I've installed them remotely without a mouse and just ssh in, but it would be nice to have access to the GNOME desktop.   So far, Hyper-V has been absolutely brilliant, but this ONE issue just makes everything they've done so right seem tarnished.  I have to imagine a great majority of people will be running production Hyper-V servers remotely.

    John- I'm experiencing the same problem as Robr, but my topology is different. Instead of going through firewalls, mine is being routed by firewalls. I use ISA 2004 at two points to create a site to site VPN tunnel. Other MMC consoles seem to work, but this Hyper-V one does not. Again, it's not going through NAT, but in a routed environment. I would like to be kept up to date also if you could. -Michael michaelsainz@(takemeout)sunsetpres.org

    Thank you very much! I would never have thought it would be so difficult to get Hyper-V Manager running with a remote connection. Two comments below.

  1. I installed the RC0 for Hyper-V and found both on the server and my Vista SP1 client that some new firewall rules had been added which looked very much like the WMI rules (same ports, etc.), but starting with "Hyper-V". I disabled the WMI firewall rules from your steps and everything still worked.
  2. The reason you can't copy and paste the firewall rules from the blog post is that the open and closing quotes are not the same ASCII character as the one on the keyboard :). I've seen this many times using Word as it replaces the quote character with fancy open and close quotes that the command prompt does not recognize.

    I couldn't get this to work until I explicitly added my user name to the appropriate steps in the server portion of this guide.  Even though that user was a member of the Administrators group on the server.  This was not enough to allow the connection. The user had to be added separately. At least on my setup. Running Server 2008 Full x64 with a client running Vista Business x86 SP1.

    Brilliant walkthrough, and quite dissapaointing that it actually needs to be this complicated! One observation and one question: Observation: You don't need to restart the server after making the changes for it to work. Just restart the "Windows Management Instrumentation" service, which will in turn restart Hyper-V for you. Much easier than a whole reboot! Question: What security issues are there now that you have enabled anonymous logon remote wmi to the admin workstations?

This is on domain (server/client)..

    John, Disable "File and Printer Sharing" on your Hyper-V server (via Windows Firewall - Exceptions) and then try using your Vista client to connect to your Hyper-V server. Do you get the following error after doing this? Error: "An error occurred while attempting to connect to server "VIRTUALSERVER". Check that the Virtual Machine Management service is running and that you are authorized to connect to the server" If you do receive this error, then I have a question that you may be able to answer: Why does Hyper-V Manager (on the Vista client) require the enabling of "File and Printer Sharing" on the Hyper-V server? Thanks, Dave

    John, I also noticed the folowing: HVRemote commands do not work on the Hyper-V server unless you are the "Built-in" Administrator. If you use another "Administrator" account or "User" account, you will receive a "Failed to call GetSecurity Descriptor" and will stop at the "Cimv2 Namespace". All HVRemote commands work fine on the Vista client. Thanks, Dave

    How come HVRemote operates in Windows Vista without having to elevate the command prompt? HVRemote runs as a standard "User" or "Administrator" without have to run in an elevated command prompt. Does the settings (ex: "Cimv2 Namespace, etc") that HVRemote needs to configure require elevated privileges to set them up properly? Thanks, Dave

    When copying and pasting netsh advfirewall firewall set rule group="Windows Management Instrumentation (WMI)" new enable=yes from the web page it uses the "wrong sort" of double-quotes. If you copy into Notepad, change the quotes and then copy/paste from Notepad it will work.

    Hi John, I run the following command on my Hyper-V server: cscript hvremote.wsf /mode:server /show ...and receive the following error: ***** Failed to call GetSecurityDescriptor ***** Giving up as not able to get the security descriptor for the cimv2 namespace This error is happening because I am not running the hvremote.wsf script in elevated mode. Could you put some error checking in the code when a user is not running a elevated command prompt (like you did with the client side). The client-side message that you created in v0.3 was something like this: “All client operations which change the configuration must be run from an elevated command prompt.” Thanks, Dave

    Hi John, I'm tired tonight. I had v0.2 on this server. I thought I had copied v0.3 on each of my Hyper-V hosts. Forgot one...I guess :+) Thanks, Dave

    Maybe one step is missing in the post (which is handled by the script), at least for Microsoft Hyper-V Server 2008. For this release, no configuration seems needed on server side, all setup has to be done on Vista. The missing step could be the cmdkey command is case of a workgroup scenario. On Vista : cmdkey /add:<server-name> /user:<admin-user-on-server> /pass:<admin-user-password>

    John, first of all congratulations for the great HVRemote tool. It rocks. Also, your articles are of great value. Thank your for putting them together. I have a weird situation here. I have two machines running on the same WORKGROUP and inside the same network segment (same IP class/net mask for both - 192.168.1.25 server e 192.168.1.7 client). I am able to connect to the server and change its configurations via Remote Management running on Vista SP1. But in the Virtual Machines group I get the message "RPC Server unavailable". And when I try to create new vms, HVRM creates de VHD file but crashes in the middle with the error above. In summary, I can change Hyper-V Server configuration (like default folders and virtual networks), but when I try to manage VMs (create, for instance) I get the RPC error. Any thoughts? Thanks again.

    One additional comment: after getting the "RPC unavailable" error and clicking on "Refresh" Hyper-V Manager sits idle with the message: "Loading virtual machines..." and nothing happens. I am running Hyper-V as a role of a Windows 2008 Server Core.

    Thanks John for taking the time to put this together!  I didn't use your HVRemote because I wanted to see what was involved to configure Hyper-V Manager. You did an excellent job!  Thanks Again!

    Wow!  I just followed these instructions, and indeed got this working.  So, hats off to you for taking the time to document and post this; I sure appreciate it. Now, as to MS, maybe they could make this a little harder, but why bother since they've pretty much aced this in the PITA department (including a reboot -- wouldn't be complete without a reboot). Thanks for this and all the other helpful posts I've found here. cheers

    Thanks for such detailed work. I've followed the examples to a "T" but this problem persists for me: Once I've connected to the Hyper-V server from the client (Vista Ent 64, SP2), I get an  RPC error. After refreshing the detail pane simply says "loading virtual machines" but nothing ever comes up. I can manage the server settings, and have even created a VM, but I cannot see them. I disabled the firewall on both server and client and the same thing happens. Any ideas? Thanks!

    Ok, at the last moment, I found the source of my problem. My the network adapter in my Vista client, running as a VM in Sun VirtualBox, was configured with NAT. Once I switched it to bridged, all worked fine. Thanks, sorry for the false alarm.
