Jennifer - you can do what you need right now. When one of our satellite offices was still in mixed mode they were running Exchange 5.0 on and NT4.0 box. This box was also a BDC (formerly the PDC until AD servers were introduced.
I recommend you upgrade your 5.5 box to SP6 (if it's not already there.) Set up an ADC between the Exchange 5.5 box and one of your AD DC's and allow replication to begin. Then when you are ready --- install a separate (preferably new/clean box) Win 2K Exch 2K server into that exchange site (remembering to run setup with the /ForestPrep and DomainPrep switches separately) - migrate your mailboxes over to the 2K box decommission the 5.5 box ---- and switch to Exchange Native Mode (which is different than Win2K [AD] NATIVE MODE). Then when you are sure you have no remaining NT 4.0 domain controllers --- switch to Windows 2000 Native Mode. Craig Craig P.

We currently have e5.5 and plan to upgrade to e2k next month. (since we aren't in native, we can't do a migrations using the adc - right?) can i setup my new exchange server (offline) with w2k and e5.5 and then upgrade to 2000 then take down the production 5.5 and put the new 2k box into production? any gotchas? can i do this? thanks!! ------------------------------------------ Thank you Jenn Fountain 215.712.5156 List info : http://www.activedir.org/mail_list.htm List FAQ : http://www.activedir.org/list_faq.htm List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/mail_list.htm List FAQ : http://www.activedir.org/list_faq.htm List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/
