Hello there, I have a quick question. I'm aware that you can't rename a Windows 2003 AD domain residing in a Forest also containing Exchange 2000 Server(s), that can be read in the MS Domain Rename docs. But I find it weird MS don't mention anything about Exchange 2003, which leads me to below question: Does this apply to Exchange 2003 as well ? Even though I personally would say yes, I ask so I know for a fact :) Regards Henrik Walther Exchange-faq.dk
