My company currently has two Exchange 5.5 SP4 servers running, both are in the same org and site and running on WinNT 4.0 SP6a machines. My problem is that I want to be able to replicate mailboxes, distribution lists, and mail to the second Exchange server so that I can easily failover to the second Exchange machine by simply swapping IP’s between the two machines. I thought this was the main advantage to having a backup in the same site as your production machine but I can’t get the replication to work and if I try to do an export/import it doesn’t create any mailboxes or distribution lists on the backup machine. Am I doing something wrong? Do I need to configure something that isn’t configured? Is it possible to get full failover capabilities between two Exchange servers? Any help would be greatly appreciated.
