I am installing an Exchange 5.5 on a W2000 server along side a W2003 Exchange enviornent that also has another 5.5 server.  This is a AD 2000 enviornment.  When prompted to install the new 5.5 it asks to join existing domain or create a new one.  I know I need a w2000 connector to talk to the 2000 enviornment but, would the one in use be sufficient?  Do I joing the domain now or later?

    Is the Exchange 2003 in Native mode or mixed mode? If its in Native mode already, you cannot link the two together.

    2003 Is working in mixed mode because there is another 5.5 along with it.  This would be the second.

    My apologies; I misread the question. Yes, you can join the new 5.5 to the existing organisation and site of the first 5.5 server. The ADC connector between your 5.5 and exchange 2003 install should handle the details for you. just make sure that replication etc is fully up to speed before hand and check it again afterwards before you make any further changes to mailboxes and accounts etc.
