Exchange 5.5 is not supported on Windows 2003 server. I don't even know if it would work.

If I install Exchange 5.5 on a Windows 2003 Server will that work in an NT 4.0 Domain Architecture? Thank again.

So the simple answer is no. You must have AD. As for your other question, Exchange 2003 will install on W2K or W2K3, but to take advantage of features like RPC over HTTP, you will need Windows 2003. -----Original Message----- From: Rosales, Mario [mailto:[EMAIL PROTECTED] Sent: Thursday, September 25, 2003 2:27 PM To: Exchange Discussions Subject: RE: Exchange 5.5 and Windows 2003 Martin, Thanks for your response. Another Question: When you say build the new Exchange Server Install 2003 and move the Mailboxes, are you saying install Exchange 2003 on a Windows 2003 box? But will that work in an NT 4.0 Domain Environment? Remember, we are still on a NT 4.0 Domain Structure and moving to AD.

Yes 2. No 3. You cant directly upgrade Exchange 5.5 to 2003. If you need to keep Exchange on the same hardware you will need to upgrade the OS to W2K, then upgrade 5.5 to 2000, then upgrade 2003 to 2003, the upgrade the OS to 2003 if you choose. The better solution would be to get a new Exchange server, install 2003 and move the mailboxes. -----Original Message----- From: Rosales, Mario [mailto:[EMAIL PROTECTED] Sent: Thursday, September 25, 2003 2:15 PM To: Exchange Discussions Subject: Exchange 5.5 and Windows 2003 Have a few questions: We are currently about to start a Migration to AD. We have a Exchange 5.5 Server on a Windows NT 4 box. We are moving the Exchange 5.5 Server to a Windows 2000 Box due to limitation on the Old Hardware. After our AD Migration we are going to upgrade to Exchange 2000 I have a few questions that I was wondering if anyone can help. 1. Will Windows 2003 Work in an Windows 2000 AD Environment 2. Will Exchange 5.5 Work on a Windows 2003 Box? 3. Will Exchange 5.5 Upgrade to Exchange 2000 on Windows 2003 Box or Exchange 5.5 to Exchange 2003 work on a Windows 2003 Box that is in a Windows 2000 AD Domain or a Windows 2003 Would appreciate any assistance. Or if you could let me know what's the best migration path to make it easier. :) Thanks for your help in advance! *************************************************************************** The contents of this communication are intended only for the addressee and may contain confidential and/or privileged material.
