some weeks ago microsoft took some changes with its RDS-components and after an automated update i can't connect to my server over internet. Only way is to connect to another pc thats in the same LAN with teamviewer and start rds -session over that pc.
i setup an virt. OS with hyper-V that i can connect via RDS over internet without problems, but connecting/login on the real machine Server 2012 R2 allways fails.
If you got an step-by-step guide that help (WITHOUT vpn) your job is done. else we could manage it together via teamviewer when i'm localy in front of the pc in our LAN, but be awared, the servers frontend-language is german.
