Guido, How about: 1) rename the NetBios name of the target AD 2) perform the migration 3) rename the NetBios name of the AD back to the original Because you are changing only NetBios name and not the DNS name, the fixups at the AD side are rather minor... Or are we talking about target AD being already production and/or W2K ? Guy

But when migrating from one NT4 domain to an AD domain which both have the same NetBios names, various issues and potential conflicts come to mind and I wonder if others had to do this in the past, who could share their experience. Think about an existing NT4 domain called CORP and another existing AD domain called CORP (with DNS=copr.company.com). And now you need to migrate all users and resources from the NT4 CORP to the AD CORP and place AD DCs into the same sites as the exising NT4 DCs... I can imagine various challenges, besides not being able to setup a trust and thus loosing various options for doing a "normal" migration. At least I have no need to register the AD domain in WINS; all clients are XP, but I know for sure that I'm going to run into various other issues (the worst one being that the account activation and the resource migration has to happend instantaneously, since resource access won't be possible accross the domains). But I'm also thinking of networking issues with and NT4 DC of the one and an AD DC of the other domain in the same ip-subnet... I wonder how others have tackled this challenge and what issues you ran into. /Guido
