I have a following setup (all machines run Windows Server 2012 with latest Windows Updates)
- 1x Remote Desktop Connection Broker, this machine runs the RDWeb application too (TSBroker)
- 1x Remote Desktop Gateway Server (TSGW)
- 3x Remote Desktop Session host machine (TSAPP01-TSAPP03
The network publication is the following:
- TCP 80 / TCP 443 -> TSBroker
- UDP 3391 -> TSGW
My actual problem is I cannot connect to the farm via RDG with mstsc client, nor with RemoteApp, nor with a well-configured manual mstsc connection. I can reach authentication stage, I can enter the username and the password, but the client says "remote desktop gateway server is temporary unavailable". Things I checked/tried:
- The connection between the farm and the client is good, client has no networking issue, DNS resolution is good
- There is a turned on Windows Firewall on machines, but the Domain profile set up to Allow/Allow, so there is no Windows Firewall restriction between machines.
- I tried to check all the logs on all machines during an unsuccessful login. Nothing written down, nor on broker, nor on gateway, nor on the session hosts. The only log i get about unsuccessful login is the following:
RDPClient_Gateway: An error was encountered when transitioning from AAStateInitializingTunnel to AAStateError in response to 6 (error code 0x800706BA).
I found near absolute nothing about this error.
There was a state when this system worked, but as it is a work-in-progress infrastructure, we had a temporary certificate on the servers. We reached that stage where we were able to replace these certificates with working ones. After it, we started experience that issues I describet above.
I do not know what is broken in this system. I have very light knowledges in Windows Server 2012, and nothing in Windows Server 2012 RDS. I would be happy for any real help what points where can I find a problem or a solution. As I am not too comfortable
in this system, please be very specific, describe me required steps one-by-one, to make sure I doing things right.
I would be very thankful for your help.
