I have a Azure VM RDS farm that consist of two servers (Win 2012 datacenter). One running the session host and the other running everything else. We have the Gateway set up for external users, and everything seemed to work just fine. But today our client noticed that if they minimize the session window (we have remoteapps published) it will disconnect in about 30 seconds. If they leave the window up it works just fine. Now this issue is only happening when somebody connects to the connection broker through the gateway. If they are on the internal network everything works just fine.
Here is what i have done so far,
- ensured that the Keep alive interval in GPedit was enabled and set to 1 on both servers
- run network monitor on all servers and clients to get insight
the clients internally are getting the keep alive from the session host
the session host is also sending keep alives to the gateway
no keep alives are being sent to the client from the gateway. and the client is not receiving any at all.
I'm open to any and all suggestions, as I've been pulling my hair out for the last 6 hours. And I thought only SharePoint could cause me this much frustration.
