This is what the instructor of our AD class told us is a good way to do it, just want to check if I may be missing anything: 1 - Build a temporary box as a NT4.0 BDC 2 - Promote the temporary box to a PDC 3 - Check replication 4 - Upgrade the temporary box to Windows 2k or 2k3 5 - Wipe out one of the existing NT4.0 BDC's and set it up from scratch with 2k or 2k3 as a member server 6 - Run DCPROMO on the member server 7 - Transfer the 5 roles to this newly promoted machine 8 - Demote the temporary box and remove it Does this sound like a good start? Right now I have the temp box setup as a NT4.0 BDC. I have 6 servers I need to bring into this newly formed W2k AD structure when all is said and done. ********************************************************** To Unsubscribe, set digest or vacation mode or view archives use the below link. http://thethin.net/win2000list.cfm
