Currently running a Windows 2000 Native domain environment with a total 7 DCs in my organization. The very first DC, lets call it DC1, running Windows Server 2000 SP4, was the very first server to be promoted in the forest and it holds all of the FSMO roles. I have just built a 2003 Server SP2 and I am looking to transfer all the FSMO roles from DC1 to the 2003 server and eventually bring all the other servers up to the 2003 domain level.
My question is what is the best way to go about starting this process. Will i be introducing any DNS or DHCP conflicts if I go ahead and promote the first 2003 Server to a DC into this existing 2000 domain. Do I need to transfer the roles as soon as I promote this DC or do I have some time. I have already had to run the adprep /forestprep and /domainprep switches in order to run the DFS tools in the R2 version. Will I need to run these again if the schema has already been updated. TIA
