Problem with 2 exchange servers for a single domain on the same subnet
Posted on 2007-07-23
I have a small client, who recently split the business into 2 parts. Both businesses are physically located in the same premises, both have an SBS2003 r2 server. file and print services are used by each business on their respective SBS server. some network devices are still shared, and thus all users are on the same subnet. Currently server1 has a problem with SMTP traffic, and is using POP connectors to an external ISP to pull down mail. All users currently use the Exchange 2003 server on Server1.
both businesses share the use of a single external domain mybusiness.com.au, and I have set up similar, but different internal domains for the SBS server mybusiness.local and mybus.local.
I moved the 2nd business users to Server2, and this worked for external mail. however, they were unable to send internal mail between Exchange server1 and Exchange Server2, and the shared devices routed mail through server1, where it queued until they failed.
lookiing for thoughts on how to set this up correctly? any ideas?
