Topology as follows:
Single AD domain with two exchange sites. Exchange 5.5 server on each site connected through site connector.
Clients are win xp sp2 with patches coming through SuS (fairly new) and Outlook 2003.
SIte 1:
Exchange 5.5 servers are running on Win 2k AD domain controler (root, master of all roles) with ADC. There is a number of other AD DC's (mixed Win 2k3 and Win2k). Exchange 5.5 is connected with exchange site connector to a site 2 exchange 5.5. This site receives mail from the net and forwards it to appropriate mailbox.
Site 2:
Exchange 5.5 server on Win2k AD DC with exchange ADC. One more AD DC (win 2k3). Talks to site 1 exchange 5.5 through site connector.
AD DC on site 1 is "primary" DC (DNS, master of all roles, DHCP).
So single AD domain and two exchange sites. 128k leased line between sites.
I have tried migration wizard from site 1 (where primary AD is). I guess we need to get it working on both sites.
I did not designed it, just installing zimbra
