Active Directory Deployment with Two Geographic Locations

[madhusd]

I currently have two AD Domains (parent - child) that are linked by a MPLS circuit. Administrative overhead is not a concern and neither is security. For maximum performance, is a single Domain with two OUs better than having two AD domains ?

Both Domains have their own exchange servers that host their respective user mailboxes. Replication takes up a lot of traffic and users who travel between offices have tough time with emails if their mailboxes are located on the other server.

What would be the ideal AD deployment in this scenario ?
Any suggestions are greatly welcome !!

I'd run a single domain with multiple OU's and maintain the separate Exchange servers at the sites.

I'm Certifiable, not cert-ified.
It just means my answers are from experience, not a book.

Thanks for the tip ! How would you convert from dual domains to single ?
