Hello,
I have RDS 2012 r2 setup and working fine with SSO enabled. Except if I create a RPD file on my desktop and I click on it, when I'm connected to the domain it logs in with my locally logged on credentials onto the RDS Host. If I go external and connect to an Internet connection, then click on the icon it says that the it didn't accept my credentials and ask me to type them again. I type them in and it works, I've set this up before and it worked externally without asking for my credentials again. I have all my server fqdm setup correctly with certs etc. but it still wn't work!!
Any help would be fantastic.
