Greetings all. I have a client who at there main site have 1 windows server 2003 server with exchange 2003 which is the root forest domain. At the remote site connected via fiber exists another server that was configured as a new tree in an existing forest for a non-contiguous name space that used the exchange at main site for mailboxes and symantec endpoint antivirus. Now we are added another server at another remote site which needs exchange access but this site will be connected via a 10mbps point-to-point wireless connection which we pre-existing. My question is, due to replication between domains in the same forest should I make this new it's own forest due to slow point-to-point connection and data replication? If I do a new forest I would obviously have to create a trust between the two forests but this would elevate speed concerns correct?
