My current configuration is Windows 2K PDC and Windows 2K BDC. I recently purcahsed a Windows 2K3 server. I tried going through all the MS whitepapers about adprep / adsiedit.msc and etc.. but the Windows 2K3 server still won’t join the domain. At this point the PDC and BDC servers both say they are ready for Windows 2K3 servers to join the domain but when i DCpromo 2K3 says 2000 envirnment is not ready for 2K3 to join.
My second option is to promote my Windows 2K BDC to PDC and then upgrade that server to Windows 2K3 remove the old PDC completely out of the equation and make the new Windows 2K3 server the BDC. Questions is if i decide to take this route what is the best way to handle this?
