    Just found this post, where a MS person states that this will not work. No explanation as to why though. http://social.technet.microsoft.com/Forums/en-US/fd4128e4-a82b-44b0-9f16-b0dfaaa0cad9/rds-2012-win8-file-associations


  2. Hello. I hope you’ll forgive me for posting this here. You had posted on http://social.technet.microsoft.com/Forums/windowsserver/en-US/1e93f528-50cd-4ec1-9bfd-27f322afa440/server-2012-rds-the-publisher-of-this-remoteapp-program-cant-be-identified?forum=winserverTS&prof=required, but I don’t think you’d see the enquiry I posted to you there.

    I’m running Server 2012, and I have not been able to suss out how to create the trusted certificates. I have a CA installed and running in our AD domain, and I have all of the RDS roles on one server. Right now I have self-signed certs, which are obviously untrusted.
    Can you please point me in the right direction for generating a certificate that I can then import into RDS so that it is trusted?

    Thank you!


    • rcmtech says:

      Just use your CA to create the certificates (assuming you’re using them internally, otherwise you’ll need to distribute your root and intermediate certs to all clients). You should have some certificate templates already configured, so just use the CA web interface to create the certificates required as per my post above. I have a “web server” certificate template and used that. There are certain requirements that the certificate must conform to, such as being able to be used for server authentication.

    Hi robincm2,

    Warning while accessing RemoteApp and Desktop Connection via GPO on VDI collection.

    “The installation of the default connection has been cancelled. A default connection cannot be used on a system that is part of a Remote Desktop Services deployment.”

    Did you guys get any workaround or fix for this know issue.


    • rcmtech says:

      No. I’m now not using Remote Desktop Session Host for providing full screen desktops partly as a result of this issue. Such a shame for Microsoft to not allow this functionality.


  4. You should not have to deploy remote apps if the user is logging into the RDS server it self because it already has the apps, that is why it is not allowed, it is redundant


    • rcmtech says:

      Perhaps if you have a very small environment. But consider this scenario: If you have RemoteApps presented from one or more sets of servers you should be able to present those to desktops running on a different set of servers. Yet, this is not possible with Remote Desktop Services. Seamlessly. It does work if you get your users to log into the RDWeb site, but why should users with a Remote Desktop have to do this when users on regular PCs can have it configured via Group Policy? It also means that Session Host desktop can’t use RemoteApp file associations. Inconsistent, for no apparently good reason.

    This is a huge pain. We have RemoteApp Session hosts running on dedicated hardware (for Matlab computations) that users need to be able to access from their Remote Desktop Session. But manually adding the feed in a user session from the same RDS deployment (but a different collection) seems to work though. I just tested it. Just not via the pre-defined “Specify default connection URL” GPO.

    Did you ever find a fix for this? We are in love with Event ID: 1026 as well.


    • rcmtech says:

      Nope. As above, I ditched using full screen Remote Desktops. My users are getting mini PCs running Windows 8.1 instead. I also found out that Lync isn’t supported on RDSH desktops. Somebody at Microsoft needs to respond to this (but I’ve yet to find any explanation).


      • bkleef says:

        Thanks for getting back to me. In our situation we have to use full screen Remote Desktops because of ancient thin clients.
        What makes it interesting is that each user on our base RDSH can add the RDWeb feed manually in Control Panel without any issue; RemoteApps are directly visible afterwards.

        Based on above it’s possible to force this URL somehow by for example a Mandatory profile or by a combination of registry entries and files/folders. Shall I keep you posted?


      • rds_techie says:

        I would be very interested in such a workaround. Having users add the feed manually on the sessions hosts works, but is far from optimal. If a solution via registry key can be found it would be quite useful. I probably should have invested time looking into it.


  8. Sandmich says:

    Thanks for the note, as I was banging my head against the wall on this (GP works fine for dedicated Windows 10, but dies on virtualized Windows 10 and Session desktops). This would seem to be counter to Microsoft’s recommended deployment strategy of separating apps from the hosting operating system so I don’t know what their deal is.

    For anyone still encountering these issues

    You can delivery Remoteapp to RDSH via a login script, like you have found GPO does not work for this solution.

    you would need to create a .WCX file which is what server 2008 did by default and then with this file run this in a .bat for example.

    rundll32.exe tsworkspace,WorkspaceSilentSetup \\location\of\file.wcx

    This can be tested from cmdline.
