Exchange 5.5 and Win 2k/2k3

By lbackman ·
I have a WinNT domain with a PDC and BDC and will upgrade to them to Win 2003 DC's. I have an Exchange 5.5 server running on a Win 2k member server. We will upgrade Exchange in the future but not immediately.
Will Exchange 5.5 work with Win 2k3?
What kind of problems am I going to need to look out for when I upgrade the Domain Controllers as far as Exchange is concerned?
What mode will 2k3 Active directory need to be run in?
Good links would be helpful.

Ok from the top.

Have you taken into account the hardware requirements for windows 2003?

now to actually try to answer your question

"Will exchange 5.5 work on win 2k3", well exchange 2000 will not work on windows 2003 so I would be very surprised if exchange 5.5 will. The schema has undergone some changes with do not allow exchange to run but I am sure if you are determined enough you would be able to find a registry hack somewhere to make it work.

Oh and just a bit about terminology, they do not consider a exchange 5.5 to 2003 to be a upgrade it is considered to be a migration.

What kind of problems might you encounter when you are going to upgrade the dc's as far as exchange is concered. Heaps refer previous because exchange 5.5 will not run on windows 2003.

Just look on the microsoft knowledge base or technet for any relevant articles.
