[ActiveDir] exchange 5.5, active directory and ADC

[Chaudhary, Amit]

Hi   This maybe a bit of topic but I was hoping to get some advice from the list.   I have a Windows 2000 active directory environment, one of my Windows 2000 servers is running exchange 5.5 (not a DC). We have been considering moving to exchange 2003, the migration method was to join exchange 2003 to the existing site, move the mailboxes and then bring down the old server. The problem is that I have come across the Active Directory Connector and I wanted to get some more information on this, as I have been told it has not been installed on my site. I.e. the 5.5 directory is not updating the active directory and vice versa.   If we were to install the Active Directory Connector, would exchange create new accounts in my AD for all the mailboxes I have in my mail system, or will it see that active directory accounts are already created? The AD accounts are created as firstname lastname, but the display names for our email accounts are lastname, firstname. What will be the overall affect on my AD of installing this connector and enabling bi-directional communication?   Regards   Amit
