    We currently have 3 categories in my company with the following details

    A- Head office with 2008R2 DC and Exchange 2010 System

    B- Remote Site with 2003 DC and Exchange 2003 System

    C Local Site with with 2008R2 DC and Exchange 2003 System

    Site A and C are currently on the same physical LAN but different Logical IP Addresses. However there is need  to achieve the following.

    1. Mail routing accross the domain A and C pass through the internet and there are regular DNS resolution problems since they share the same router. we will like a situation where mail routing is done without the internet. Mails across the domains can be resolved internally.

    2. we will like to also achieve DNS resolution for the hosts in the 3 domains without issue.

    Please help.

    Hi IFINITEM,

    Thanks for posting here.

    >1. Mail routing accross the domain A and C pass through the internet and there are regular DNS resolution problems since they share the same router. we will like a situation where mail routing is done without the internet. Mails across the domains can be resolved internally.

    So are these two mail systems where in two sites are using same name space?

    Using the Receive Connectors in Exchange system will work.

    Do you mean want to route the mail through internal networking instead over internet ?
