I have an Exchange 2010 SP1 RU6 environment with 3 servers on 2008 R2 OS.
1 - MBX/DAG, HTS, CAS
2 - MBX/DAG, HTS, CAS
3 - HTS, CAS
When I shut down one server the mailbox DB in the DAG move without issue but the clients continue to try and connect the the downed server as their CAS server. When I user the "Get-MailboxDatabase |fl identity, RpcClientAccessserver" command it shows the database connected to the same server despite the fact that it is shutdown.
The questions is. How do I get the CAS server to automatically change / How do I get the client to connect to the other CAS server automatically?
