I have a DAG setup spread over two physical sites and broken up with two AD sites, connected via MPLS. The witness server is located with the DR server in the other location. Last night we did a test of the fail-over capability and it did not work.
I am just wondering if I am missing something, here is my scenario:
Exchange Server 1 - All Roles except Edge Transport and 4 Mounted DB's with 1 Public Folder DB
Exchange Server 2 - All Roles except Edge Transport and 4 Healthy Copies with 1 unmounted Public Folder DB
In my test I shutdown Exchange Server 1 and waited about 10 minutes and tried to open my Outlook Client but it could not find a server. I thought the fail over would be automatic but maybe it is not.
