  • I'm connecting using RDP 8.1 and all settings on the client are set to enable remotefx and allow automatic network detection. I can connect to a 2012 server and not get the message below. It only happens on the 2012 R2 server and both servers are using the same group policy.

  • No change.

    I've disjoined it from the domain and connected at a 1366x768 resolution. I was connecting at a 1024x768 previously.

  • Hi bryans2k,

    As Susie suggested, you may need to submit a service request. Therefore, may I obtain your permission to temporary archive this case?

    If there is any question, please feel free to let us know.

    Thanks.

  • hi all ,

    Were you able to solve the problem...I'm experiencing the same issue: W2k12R2 connecting by using a RDP8.1 client:

    The network characteristics detection function has been disabled

    Thx

  • No because they wanted me to submit a ticket which I don't currently have time for as it was just a test system.

    Thanks,

  • Just an update, I was able to get it to stop appearing when I used group policy to force network detection to be enabled.

  • So my conclusion is that network detection is some how broken in R2. I have Windows 8 Pro clients that work fine with server 2012 and don't with 2012 R2. When I disable network detection they begin to half way work again but are still not performing at server 2012's level. The network detection seems to also break other clients that run on thin clients such as Wyse.

    Hi Bryan

    Could you provide details on how you accomplished this?

    I'm running Hyper-V 2012 R2 (workgroup mode), trying to connect from Win8.1 Pro. Same trouble.

    Thanks,
