Brennan Robotics has hired you to plan the upgrade of their Windows NT 4 domain to a Windows 2000 Active Directory domain. They currently have a primary domain controller running on a dual Pentium 500 MHz system. They also have three backup domain controllers, two running on single Pentium 133 MHz system, the other on a Pentium 100 MHz. The have a few dozen Windows NT Workstation 4.0 and Windows 98 desktop systems. The Windows NT Workstations are running on Pentium 133 MHz systems and the Windows 98 machines are running Pentium 100 MHz processors. They’d like to upgrade all PDC and BDC systems to Windows 2000 domain controllers, using their existing hardware. Once you’ve gotten as many servers running Windows 2000 as possible, they’d like you to upgrade all the Windows NT and Windows 98 systems to Windows 2000 Professional so the domain can be run in Windows 2000 native mode. This should be done without any further hardware expenditure. If you can’t upgrade the Windows 98 machines and therefore can’t run in Windows 2000 native mode without a hardware upgrade, you should at least set up a domain dfs root, so the Windows 98 machines can take advantage of the mixed mode Active Directory capabilities of Windows 2000.
How many backup domain controllers should be upgraded to Windows 2000 Server before the primary domain controller?
