Windows NT 4.0 Reference Material.
Serving the NT 4.0 User Communitity Since November 2003.


The information presented on this web site is intended to assist those who still maintain a PC running the Microsoft Windows NT 4.0 (Workstation or Server) Operating System.

Most of the data here has been accumulated by the author as various problems relating to the operation of NT 4.0 Workstation were diagnosed and rectified. As such, much of the material presented primarily deals with NT 4.0 Workstation, although in most cases it would be equally relevant in a NT 4.0 Server environment.

I have primarily concentrated on the operation of the OS itself, so problems relating to interaction / performance of applications running on NT 4.0 are not extensively detailed here.

This site contains lots of links to specific files and pages on other web sites on the net. Whilst I attempt to ensure that all the links function correctly, as you can appreciate, the net is a dynamic place and files often get removed, renamed or relocated. If you encounter a 'dead link', have additional information, or believe you have found an error or omission in this site, please contact the author (Calvin) at

Also be aware that ANY file downloaded from the internet poses a security risk to your system. Take all normal steps that you employ when dealing with material of unknown origin. The minimum expected safety procedure would be scanning the files with an up-to-date virus scanner before use.
