We plan to replace our Win 2000 DC. When I say replace I refere to both, hardware and OS which will be Win 2003 R2 Standard Edition. The steps we want to follow are:
-run R2 ADPREP on the 2000 DC from the 2nd disc of the R2 CD (Cmpnentsr2adprep)
-DCPROMO new server as a domain controller.
-Wait for the AD stuff to replicate. Move the FSMO roles to the new w2003 box.
-Demote the old server.
The question is: “Is this going to have any impact on my 2003 Exchange Server(runs on different machine than DC and OS is w2003 R2)?”. Do I have to rerun the adprep /forestprep and adprep /domainprep on the new DC for the Exchange Server?.
