Exchange server failover
Posted on 2006-06-22
I am currently administering a network where we have two separate locations, each with their own exchange server linked via point-to-point T1's. As we are set up, site A is the "gateway" mail server for the domain, hosting mailboxes for users in location A and forwarding messages to the exchange server at location B where those users have their mailboxes located. This works well up until the point where we lose power/internet connection/server crashes in location A. Then no one in location B is able to send/receive email. I was wondering if it's possible to setup location B as a secondary MX for the domain and have it configured to send/receive email for the domain should location A (the primary MX for the domain) become unavailable/crash. Hopefully this isn't too confusing for one of you to help me out with.
