How can I replace a master domain controller (on a new machine)?

Well, presume with 'master' you mean the DC with the forest-wide roles (like GC). After all ADS doesn't have a system with PDC etc.
1) Install the new machine with W2K, and run DCPROMO
2) With MMC (think it is 'Active Directory sites and services'), transfer all forest-wide roles to the new machine. Wait some time (between minutes and hours) until this has come into full effect due to replication.
3) Run DCPROMO on old master to demote to normal server. (Actually, if it finds any global roles left there it will warn you...).
4) Remove from LAN.

Have fun,
