I have a Microsoft Exchange 2010 on a server running all the roles on the same Windows 2008 R2 server (not Edge role though).
I have 2 NICs and I want to tell Exchange to use a specific NIC e.g. NIC1. In the route of the Server configuration in External DNS lookup I have specified to us DNS settings from NIC1. In the Organisation Configuration, Hub Transport Role the send settings the network settings are set to use DNS MX record lookup with the tick box at bottom to use external dns settings is ticked?
Where am I going wrong please as the server is using NIC2 to send out email?
