Perhaps you’ve configured RDS 2012 and are using the new Active/Active Connection Broker technology. Perhaps like me you selected a name during the HA configuration for DNS round robin name that you no longer want to use? If you attempt to edit the Deployment Properties you won’t be able to change this value.
Well this frustrated me at first but I was able to find the Powershell cmdlet that allows you to modify this after deployment.
Thanks to this thread on the Microsoft Blogs site http://blogs.msdn.com/b/rds/archive/2012/06/27/rd-connection-broker-high-availability-in-windows-server-2012.aspx
The Powershell Cmdlet is:
Set-RDClientAccessName -ConnectionBroker <ActiveManagementServer name> -ClientAccessName <New DNS RR Name>
Run that and you’ll be squared away! I officially take back my hulk smash RDS 2012 comment now. 🙂
