We have several VMware Virtual machines. All servers are Windows Server 2012 R2 Remote Desktop servers. Normal applications are installed like Office and we are using AppV packages to deploy applications like Navision etc.
We are using Automation Machine for deployment and we use VMware UEM for user settings.
The problem we have is intermittent unresponsiveness of one of the RDS servers . When this happens the servermanager application on the connection broker servers are no longer responding, and if we close and reopen the Servermanager we see that one of the servers state is “inaccessible”. New user sessions freeze during startup on the welcome screen. CRTL+ALT+END doesn’t work, logging in to the console doesn’t work.
At that point nobody can login on any RDS server. We also cannot control other RDS machines anymore because the whole collection is related to that not responding server. Which does not give us the option to see which users are logged in on that specific server so we cannot send a message to the user to logoff. The only solution then is to hard reboot the faulty RDS server.
We have searched windows event logs for some answers but we haven’t found any useful information.
1 – What causes random freezes of the RDS servers.
2 – How can we avoid and keep access to a working server manager
3 – When one RDS is not responding the connection broker should redirect users to another RDS instead of the faulty one.
