Hi guys We have server 2000 sp4 which is additional domain now, has WINS,DHCP,DNS server roles, and I have also first DC Server 2003 R2 which is DNS,WINS, global Cat, I would like to get rid of server 2000 and get new one,(2008 r2), what I would like to do is 2008 R2 is First DC with (DNS,active directory, DHCP) and 2003 is secodary additional DC, Can you advise me what kind of scenerio I should be planning.

Hi , I would first plan for domain restructuring using windows 2008 R2 as domain controller. even before understanding the process involved ( transitioning or inplace upgrade ) i would re design and move to single forest architecture. I understand that you are having 2 domains domain a - windows 2003 ( forest ) domain b - windows 2000 you are adding additional domain in the existing windows 2003 forest , for which the first step would be a) prepare the forest for win 2008 R2 by running running adprep/forestprep ( this is used to extend the ad schema ) , browse to windows 2008 r2 cd under sources/adprep b) perform adprep/forestprep , adprep /domainprep/gpprep , adprep/domainprep , adprep/rodcprep. follow the below blog http://blogs.dirteam.com/blogs/sanderberkouwer/archive/2008/04/08/upgrading

Thank you for your answer, How about the DHCP server on Server 2000,Do you think should I migrate DHCP role to 2003 then migrate to 2008? or Should I kill the all roles on server 2000 because it is a secondary domain then I can reconfigure DHCP on 2008, What i means was basicly I kill the 2000(power -off) then install 2008, then make it primary DC. TY

Hi, I think reconfigure DHCP on 2008 is also available. For migrate DHCP database, you can refer following step-by-step article: How to move a DHCP database from a computer that is running Windows NT Server 4.0, Windows 2000, or Windows Server 2003 to a computer that is running Windows Server 2003 http://support.microsoft.com/kb/325473Shaon Shan| TechNet Subscriber Support in forum| If you have any feedback on our support, please contact tngfb@microsoft.com
