  1. I had this error on my PC running Windows 7, whenever leaving the office domain this error emerged when using RDP.

    For me it seemed to be on the client side, more specific I changed to things and it started working again.

    1. Internet options
    A) Open "Network and Sharing center"
    B) "Internet options" then "Security" tab
    C) There highlight "Internet"
    D) Make shure the option "Enable Protected mode" is not ticked

    2. Firewall settings
    A) Open "Network and Sharing center"
    B) Windows firewall
    C) Make shure everything is green as recommended by Microsoft.
