Hello I'm in kind of a situation here.
I've 2 Networks that I'm going to join.
Network 1 consists of a SBS server with Exchange for domain A.
Network 2 consists of several servers 2003 R2 including also an Exchange Server installed on the GC
(I know not the best solution and it might even make the solution to my question harder a company called *** first letter is H and last is a B did that for us oh and the middle letter is next to the P)
Physically those 2 networks are now connected by LAN.
All the data is in place and all user accounts / computers are in place except for one thing: Email.
The exchange server in network 2 will be responsible for all email.
(Email is now being deliverd in network 1 to an IP directly pointing to the SBS server!) <== Not Secure!
What is the best way to go?
I thought installing a second NIC on the Exchange server and assign it the same IP as in network 1 would do the trick.
But I'm a bit scared if this will work. Because my DC will become multihomed.
I've enabled DNS to listen only on the internal IP so that should be ok.
I love this solution because it will enable me to switch mail server without having to wait for DNS to update.
Has anyone experience with this kind of setup? or has a much better Idea on how to proceed?
Thanks for Reading!!!
