We have the following situations:
1. windows 2000 Dcs and windows 2000 member servers
2. exchange server 2003 on Windows 2000 member server

We want to upgrade all Windows 2000 servers to Windows 2003 servers, and all Windows DCs will be upgrade to Windows 2003 DCs.

What are the proper steps that we should take?

Here are some links that should get you going for upgrading a 2000 domain to 2003:

Quote from the top of this article: "Several glossy Microsoft presenters have stated that all you need to do to complete a Windows 2003 Domain upgrade is run ADPREP and then upgrade away.  This may work for very small / simple environments but it is definitely not good advice for most companies.  After upgrading five servers in two unrelated domains and installing many fresh copies of 2003 I can say that I personally would not skip a single step in the process I have developed below."

How can I transfer some or all of the FSMO Roles from one DC to another?

Ok... what about my comment failed to guide you in your migration process - when you give a B grade and no so much as a comment asking me to clarify something, that doesn't seem appropriate to me... how about you vsg375?

hi leew,

That is why I went for a delete - no refund, precisely because I thought that although you gave valuable information, no elements from the author confirmed that it solved the problem.

The author seems to have accepted the answer, but I tend to agree with you, no need for clarification in such a case doesn't seem appropriate to me either.

We all know that points are not an issue here, our main concern is to give appropriate and documented answers. I'll leave the final decision to the mods.
