Using Windows 2000 server as a BDC in an NT Domain

No, this cannot be easily done, as you cannot promote a Win2000 server to
BDC in an NT4 domain. What you could do is to temporary use a couple of
client computers as backup BDC's while upgrading your current PDC. Before
you start the upgrade, you probably would take one BDC off line as a
fallback option if anything would go wrong.

SUMMARY
This article describes methods you can use to upgrade a Microsoft Windows
NT 4.0-based primary domain controller (PDC) to a Windows 2000-based domain
controller. The first step in the domain upgrade process is to upgrade the
PDC to Windows 2000 Server. Use one of the following methods to upgrade the
Windows NT 4.0-based PDC to a Windows 2000-based domain controller.

back to the top
Upgrade an Existing NT 4.0 PDC to Windows 2000
Synchronize all the backup domain controllers (BDCs) in the domain so that
they are completely up-to-date. Consider taking one of the BDCs offline to
preserve a replica of the Security Accounts Manager (SAM).
Make sure that no unnecessary programs are running before you go to the
next step. For example, make sure that anti-virus software is disabled.
Make sure that there is no DNS suffix configured in the TCP/IP properties
for the local area connection unless you are running a slipstreamed copy of
Windows 2000 that includes Windows 2000 Service Pack 3 (SP3).
Insert the Windows 2000 Server or Advanced Server CD-ROM in the CD-ROM
drive on the PDC. The Windows 2000 Installation Wizard starts and then asks
whether you want to upgrade the system to Windows 2000. Click Yes.
When the wizard asks whether you to upgrade the system or create a new
installation, click Next to upgrade.
Accept the license agreement, and then click Next.
Click Upgrade the file system (to NTFS5), and then click Next.
After the system copies necessary system files and then restarts, the rest
of the upgrade process runs automatically.
After the upgrade is complete, the server restarts, and then the Active
Directory Installation Wizard starts automatically. In the wizard, specify
the appropriate Active Directory options.
back to the top
Upgrade a New NT 4.0 Installation to Windows 2000
Install Windows NT Server 4.0. During the installation, specify the options
necessary to make the new computer a backup domain controller.
In Server Manager, promote the BDC to PDC.
Check to make sure that there are no errors in the event logs and that SAM
replication is completing successfully.
Use the steps that are listed Method 1 to upgrade the PDC to Windows 2000.
