I am having a major issue using RDP to connect though a gateway server. I have tried every trick in the book including building a windows 7 image all with the same results. I have tested multiple LMCompatibility registry entries and find RDP fully functional connecting using standard methods and even computers using the new Network Level Authentication. I'm having absolutely no luck with a gateway server and i cant understand why. It seems like a missing DLL file or something of that nature. Does anyone have any kind of clue how to go about this?
