Upgrading Clients running Windows NT Workstation 3.51 or 4.0
Because Windows NT Workstation 3.51, Windows NT Workstation 4.0, and Windows 2000 Professional share common registry, file system, security, and operating system kernel structures, nearly all applications that run on Windows NT
Workstation 4.0 will run without modification on Windows 2000 Professional. In addition, upgrading from Windows NT Workstation to Windows 2000 Professional is easier than upgrading from other Windows operating systems
for of the following reasons:
Almost all peripherals and devices that work with Windows NT Workstation 4.0 will work with Windows 2000 Professional.
The version of NTFS used in Windows NT Workstation 4.0 is transparently upgraded to the version of NTFS used in Windows 2000 Professional during the upgrade process.
There are some differences between the version of NTFS used by Windows NT 4.0 operating systems (NTFS 4) and Windows 2000 operating systems (NTFS 5). This may prevent some of the programs you have used in
Windows NT 4.0 from working properly in Windows 2000.
For example, anti-virus programs that work in Windows NT 4.0 may not be able to handle "reparse points" that they might encounter if you have created Volume Mount Points. This incompatibility may not be reported by the Upgrade Evaluation tool.
Setup compatibility report
The Windows 2000 Setup Wizard generates a compatibility report similar to the reports that are generated on client computers running Windows2000 and Windows 98.
This report is automatically saved in the systemroot folder in a file called Winnt32.log, as shown below.
If the upgrade process stops due to hardware incompatibility, check this log to determine the source of the problem.
Performing the upgrade
