I am currently running a native W2003 forest with 2 domain controllers - obviously both win2003 machines. DC1 is the primary domain controller with all the FSMO roles. DC2 is an older machine that I will eventually decommission once the newer win2008 domain controller is in place.
The win2008 machine, DC3, is currently a member server of my domain. In order to make the win2008 a domain controller, I understand that I should do the following-
1. adprep /forestprep
2. adprep /domainprep
Both these 2 steps should be run on DC1?
Can someone kindly also highlight any pitfalls to look out for before I do dcpromo on DC3?
