I have a server I'm attempting to deploy Remote Desktop Session Host to (Terminal Services). I have never done this before. I followed the guide on TechNet. I set up the licensing server on the same server, imported the CALs from an Open License agreement. It shows 12 CALs, which is how it should be. The licensing mode says "Per User" as it should. Everything has green checkmarks. Licensing diagnosis looks good -- no errors. Yet, I can't log on more than two concurrent sessions. It's acting as if it's still in "administrator mode" and not terminal server mode. I checked the clients to make sure they aren't using "/admin" and they aren't. I am always asked to disconnect somebody if the concurrent sessions exceeds two.
This is the first time I've deployed RDS. I must have missed a step somewhere! How do I begin to diagnose this? The event viewer doesn't show anything interesting related to Remote Desktop in either the application, system, security, or specific remote desktop logs. I imagine there must be some log somewhere that is saying "such and such is not able to do something. check such and such" but I can't find it.
I hope some pro out there can point me in the right direction to diagnose this. I'm not sure where to begin. :-)
Some things I've found so far that MIGHT be part of the issue:
- This server is a demoted domain controller. Is it possible some residual domain controller permissions / registry settings are getting in the way? It is now a member server and was demoted successfully with no issue.
- I have a bunch of DCOM errors in system. I'm not sure if it's related or not. A bunch of 10009 errors, DCOM was unable to communicate with the computer xxxxxxx using any of the configured protocols. It doesn't seem to coincide with logons, so I'm thinking it might be a red herring. Not sure, though.
