We have 2 2012 servers configured as RDS servers in high availability mode. We are serving up a single application as a RemoteApp.
This morning we had a networking issue and one of the servers was unreachable. (If it's relevant, the server didn't issue any NIC or connection errors. It continued running just fine. It just stopped pinging, in or out. We fixed it by plugging into a different switch.)
During the outage, users with open connections on the working server were fine, but users on the unreachable server couldn't do anything. Is there something we should have done to allow those users to connect to the working server, or is this evidence that my configuration is wrong somewhere?
