Hi,
I've just installed RDSH role on server 2012 and am trying to connect to it from Windows 8 machine encountering the following error:
Your computer can't connect to the remote computer because the Connection Broker couldn't validate the settings specified in your RDP file. Contact your network administrator for assistance.
I don't have any custom configuration in my RDP I just launch it from run "mstsc" and enter server name, username and try to connect.
