I have two sites. Site A(Los Angeles) has Active Directory, Site B(San Diego) has a DC that is aprart of forest but configured on different sites for replication purposes. Site A has Exchange Server 2000. Site B does not.
My main problem is that when the VPN or Internet goes down on either side, email users on Site B are down. How can I configure Exchange to work on Site B? Do I install Exchange Server on the Site B site? But how, how would I configure them to share the same DB? Please be specific and detailed as I will raise the points.
Also would it be the same if I upgraded to Exchange Server 2003. Would there be any benefit? I would rather stay with Exchange 2000.
