Windows
NT SAM database is a flat database. And windows 2000 active directory database
is a hierarchical database.
In Windows NT only PDC is having writable copy of SAM database but the BDC is only having read only database. In case of Windows 2000 both DC and ADC is having write copy of the database.
Windows NT will not support FAT32 file system. Windows 2000 supports FAT32.
Default authentication protocol in NT is NTLM (NT LAN manager). In windows 2000 default authentication protocol is Kerberos V5.

many more features introduced in windows 2000, those are not Windows NT.
