Re: Windows 2003 migration in windows 2008

Hello ,

As said before, 2 domains with the same NetBIOS name can not create a trust,
which is needed for Active directory migration, see also here:
http://www.eggheadcafe.com/software/...o-domains.aspx

So you have to rename one domain before starting the migration.
