Remote to server and workstation RRS feed

  • Question

  • I setup a small system running Server 2008 Standard Edition with SP1.  The network has 5 Windows 7 pro clients.  When I set it up I configured the server for Remote Desktop and was able to remote into the server.  I also setup two workstation for remote desktop.  It worked fine and then the server quit connecting with the following error:  "The remote computer disconnected the because of an error in the licensing protocol."  Reading up on this it seems like I need a RDS CAL.  So I have some questions:

    1.  Does Server 2008 not come with a single RDS CAL?

    2.  Do I need more than 1 CAL to access both the server and the workstaions?

    3.  What other options do I have for controlling the server and workstations?

  • You may try to remove the TS license from the client. This works in windows 2003. This post has more details.

  • Hi,

    Thank you for your post here.

    From the description, you add the Remote Desktop session host service on the Windows Server 2008 server and get the license errors when RDP client attempt to connect.

    1.  Does Server 2008 not come with a single RDS CAL?

    2.  Do I need more than 1 CAL to access both the server and the workstaions?

    If you have toggled Remote Desktop Service to Application Server mode, you will have to add license server and purchase RDS Client Access License (either per-Device or per-user license).

    If you configure the Remote Desktop Service into Remote Administration mode which is designed for using the RDP client as an administration tool. You can have 2 RDP connection to the server simultaneity without any license installed.

    When you toggle Terminal Services to Application Server mode, some programs may stop working

    To resolve the issue, please double check:

    1. Have you added the license server in the domain?

    2. Have you installed any RDS Client Access License for RDP clients?

    Troubleshooting Remote Desktop Licensing Error Messages---> The remote computer disconnected the session because of an error in the licensing protocol. Please try connecting to the remote computer again or contact your server administrator.

    3.  What other options do I have for controlling the server and workstations?

    If you want to admin server/workstation through RDP (less than 2 simultaneity RDP connection to the computer), there is no need for you to install the RDP session host role (Known as the Application Server mode TS) in the domain. Otherwise, you may have to purchase RDS Client Access License to legally take advantage of RDP service.
