What? You most certainly can run Exchange 5.5 on NT4 (or 2000 server for that matter) in an AD domain. You don't even need the DS client to do so.
If I'm understanding the original question correctly, you want to upgrade your PDC to win2k creating (or joining) an AD forest. You want to leave your exchange 5.5 server, which is presumably a member of the upgraded domain, running NT4. Correct? This will work just fine. You could upgrade the exchange 5.5 server to windows 2000, but I wouldn't bother. Build a new win2k server, install E2K, joining your existing exchange org. Migrate your mailboxes to the new server, retire the old. There's lots of little details you have to pay attention to along the way, but MS has tons of documents available to step you through the whole process. -----Original Message----- From: Bingel, Chris [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 06, 2003 1:28 PM To: Exchange Discussions Subject: RE: Exchange Server 5.5 and Win 2000 network You can't run it with the AD client on NT4? -----Original Message----- From: Woodruff, Michael [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 06, 2003 1:27 PM To: Exchange Discussions Subject: RE: Exchange Server 5.5 and Win 2000 network Its not only possible, its required. -----Original Message----- From: Keith Boettcher [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 06, 2003 1:20 PM To: Exchange Discussions Subject: Exchange Server 5.5 and Win 2000 network We are changing our Windows NT network to Win2K. We have a procedure for upgrading NT PDCs to Win2K Active Directory with DNS, etc. How will our Exchange 5.5 server on an NT server box work with this? Should we upgrade that box from NT server to Win2K server and still run Exchange 5.5 on it? We want to upgrade to Win2K before we upgrade to Exchange 2000. Is this possible? What are the dangers?
