Windows NT/2000 AD Migration
Posted on 2004-10-29
I am currently the admin of a Win2k/WinNT mixed mode domain. The root was originally called abc.com on NT4.0. About 2 years ago (before I started at this company) a NT box was upgraded to 2K to take advantage of active directory. When the 2K box was added instead of using abc.com the domain was called corp.abc.com.
The corp.abc.com pc is running dns/wins services and is currently seen as the Primary DC by the last NT box on my network. When I add pc's to the domain I type in abc.com and it joins the domain, but when I check the fqdn of the pc is says computer.corp.abc.com. Also, when I am on the 2k box and open domain users and computer the root domain is listed as corp.abc.com. When I look at users and computers on the NT box they are listed in abc.com domain.
Basically the question I want to know is,
What steps do I need to take to get the domain name back to abc.com without having to start a new domain from scratch? The NT box is still listed as abc.com domain without the corp. Is it possible to create a NT machine as a BDC, then upgrade it to PDC and do a Win2k migration? Will this give me the option to change the FQDN and will this update all the computers to be
Then I will just run dcpromo on the other domain controllers to get rid or the corp.abc.com I have been reading TechNet and have been searching Google for about 2 weeks but haven't found anything that is exactly like my situation. Any help is appreciated. Thanks
