My mind has gone blank for the moment sorry folks this is a silly question but.... We have many exchange 2000 servers and we want two dedicated IMS servers one as a standby in case the other fails (as we used to on Exchange 5.5). How do would you set this up? My guess is ..... Mailbox servers with no changes to the virtual smtp server Two IMS servers with an smtp connector each with the address space of *, one with a cost of 1 and the other server with a cost of 10. Each SMTP connector lists itself as the local bridgehead and the same smart host record. Is this correct? Regards Leo (Friday at last)
