Promote and demote a domain controller windows server 2008

-

hello everyone.

i have read the information in the technet library about promote , demote domain controllers, however, is the first time i'll it in a production environment and want to make sure will work properly.

i have in my organization single site and a single domain, i have 2 servers running domain controllers both windows server 2008, both global catalog. they not really servers one is a conventional pc and the other a workstation. the pc is the primary domain controller. i have now the opportunity place a hp server to replace this pc because is not very reliable.

from understand must use dcpromo.exe in this new server and put a secondary domain controller. after completing this process, i should move the operations master role to new server and then use dcpromo.exe in pc , remove the active directory and that's it.

is this all i need do, how long after configure the new server i can demote pc, how long it takes the correct replication and transfer of roles and test can i can perform to verify that running well.

what dhcp , dns settings. there other role need transfer.


any help is welcome.

thanks.

so want add 2008 dc...you don't want 2008 r2.  steps different.

i'll go adding 2008 per question.  so yes dcpromo , make additional dc in current domain. 

during dcpromo process should select box dns server , global catalog.  then after promotion have new dc/dns/gc.   

update clients (static , dhcp) use new box dns.

you can transfer fsmo roles new box.

use these procedures move dhcp database   http://blogs.technet.com/b/networking/archive/2008/06/27/steps-to-move-a-dhcp-database-from-a-windows-server-2003-or-2008-to-another-windows-server-2008-machine.aspx

 

one confident transferred check health of new dc using tools dcdiag/repadmin/event logs.  when things ok use dcpromo demote old dc

 

thanks
