I have a w2k sp4 domain; myDomain.org that includes an e2k Version 6.0 Build 6249.4:sp3 server hosting email for myDomain.org. I want to upgrade all to w2k3, e2k3 and modify the domain name to myDomain.local and am looking for the best/quickest method. The deployment guide says: Determine Domain Controller Upgrade Order "http://www.microsoft.com/resources/documentation/WindowsServ/2003/all/d eployguide/en-us/Default.asp?url=/resources/documentation/WindowsServ/20 03/all/deployguide/en-us/dssbf_upwn_wgot.asp" Do you get a chance to rename the domain as in a NT4 to w2k domain controller upgrade? Thanks all.
