I'm trying to install a Remote Desktop Gateway into my domain, but I am running into a serious road-block... when I load RD Gateway Manager to configure the service, there is nothing to configure because it won't load my server into the console. When I try to connect to it manually, it returns the following error:
"Unable to read RD Gateway Server Settings"
There are no errors or warnings in Event Viewer. I can verify that C:\Windows\System32\tsgateway\rap.xml exists and is readable. I can verify that Network Policy does have a TS_CAP_01 policy and it is enabled. A valid certificate was applied during setup (and I've also tried choosing ask me later).
I have already tried uninstalling and reinstalling the role service (including manually verifying that the policies are removed). I also have this working on another domain server, so I'm at a loss for what to look for... How can I resolve this so that I can finish configuring the service?
