I recently set up Remote Desktop Services on Server 2012. Everything is working except connecting RemoteApp externally (through RD Gateway). When connecting to RemoteApp, I get the following error:
RemoteApp Disconnected - Your computer can't connect to the remote computer because an error occurred on the remote computer that you want to connect to. Contact your network administrator for assistance.
I have researched this error and can't seem to figure it out. I'm using a self-issued certificate. I've installed the certificates on the client machine and I can connect via Remote Desktop externally without any certificate warnings. If I uncheck "Bypass RD Gateway server for local addresses" then I also see the same error internally. So it must be a configuration or certificate issue in RD Gateway? We plan to purchase a public certificate, but I wanted to see this all working first. Would a public cert resolve the issue? Any suggestions? This is a very basic installation of RDS. All Remote Desktop roles (except Licensing) are installed a single machine. Can I use RD Web Access & remoteApp without RD Gateway as we used to do in Server 2008?
