Hell, please follow http://msmvps.com/blogs/mweber/archive/2010/02/10/upgrading-an-active-directory-domain-from-windows-server-2003-to-windows-server-2008-or-windows-server-2008-r2.aspx to add a new DC to the existing domain. I can see no reason to keep the machine names but if you really will do it see: http://msmvps.com/blogs/mweber/archive/2010/02/13/upgrade-a-domain-controller-to-a-new-operating-system-version-and-keep-the-name.aspxBest regards Meinolf Weber MVP, MCP, MCTS Microsoft MVP - Directory Services My Blog: http://msmvps.com/blogs/mweber/ Disclaimer: This posting is provided AS IS with no warranties or guarantees and confers no rights.

One more clarification, Shall I need to rejoin , whole 300 XP clients to new 2008 DC for client lo-gin ?

Thanks for fast reply...

No you don't have to rejoin your clients, they will be able to authenticate without any issues, you may have to change the DNS IP Address on the clients to Windows 2008 DC's IP(If you do not keep the same IP address as that of your old 2003 DC.Thanks and Regards, Mukesh.
