Hi forum members, I have a weird issue going on with a high availability Server 2012 R2 setup.
The users of this company are connecting trough Remote Desktop Connection in- and outside the organization. All the inbound connection inside the organization goes perfect, the servers are load-balancing the sessions and uses the two session hosts to connect.
The users are connecting with the rds using round robin with hostname remote.customer.com

So it's not possible to start a remote desktop connection from external location when the broker is trying to connect with server 2.
If I check the eventviewer on server 2 it shows me the following error: "Failed to create KVP sessions string. Error Code 0x8007007A"
Current setup:
Server 1 Roles:
- RDS Connection Broker
- RDS License Manager/Server (Per device cal)
- RDS Gateway
- Session Host
Server 2 Roles:
- Session Host
Server 3 Roles:
- SQL Connection Broker
The customer uses a per device cal. All the calls are stored on Server 1. I've also forced the License server on Server 2 with a group policy.
Could someone please advise what settings to check and change? Many thanks in advance.
