Hello,
We have changed our Remote Desktop Connection Broker to High Availability, but there was still only one Remote Desktop Connection Broker. Therefore the next step was to add a second Remote Desktop Connection Broker.
I added the server by wizard and the installation started, but failed with error message (original/translated):
Die Windows-Firewallausnahme für die Windows-Verwaltungsinstrumentation konnte nicht auf "SRV2.FOB.LOCAL" erstellt werden.
The Windows Firewall exception for the Windows Management Instrumentation failed on "SRV2.FOB.LOCAL" are created.
You see, we have a german installation. However, I see on the server, all new services were installed without problem. All services, like internal database started and are running. If I try the wizard again, it stop exactly with the same error message. I tried a restart of the server with no help. Windows Firewall is running and I see six firewall rules for Windows Management Instrumation. That is the same number with the other server which already have "Remote Desktop Connection Broker".
We use only Windows Server 2012 R2 for Remote Desktop Services. There are no older systems. By the way, our DC use also Windows Server 2012 R2 - forest and domain level is the same.
Please for help.
regards, Reisenhofer Andreas
