If possible, upgrade to Windows NT 4.0. If this is not possible, follow these steps to improve the security of the system.

  1. Install Windows NT 4.0 Service Pack 6a if you have not done so already.

  2. Install Windows NT 4.0 Security Roll-up. This must be installed after Windows NT 4.0 Service Pack 6a.

  3. Visit the Microsoft Update site and install the latest critical updates. Some updates must be installed alone and will require a reboot. Visit Microsoft Update as many times as necessary to install all critical updates.

  4. Follow the Microsoft Windows NT 4.0 Server Baseline Security Checklist.

  5. Keep up with the latest security patches by using the Security Bulletins Search.

  6. Update your anti-virus tools and signature files from viruses. Check out the Virus Alerts regularly.

  7. Read the Securing Microsoft Windows NT Installation paper.

  8. Use the Baseline Security Analyzer from a Windows 2000 or Windows XP system to scan and evaluate the security of your Windows NT 4.0 Server. Specifically, identify and install missing updates as necessary.

  9. To secure your Web servers (IIS 4.0), see Securing IIS 4.0 Resource Guide.

Ongoing Security Maintenance

Without ongoing maintenance, your system can become vulnerable to new forms of attacks. Further, the security of your system will degrade over time due to human error of administrators managing the system. Follow these recommended steps on a regular basis:

  1. Use the Baseline Security Analyzer regularly to scan and evaluate the security of your system.

  2. Subscribe to the Microsoft Security Notification Service. This is a free email notification service that Microsoft uses to send information to subscribers about the security of Microsoft products.

  3. As new security fixes become available, it is important to apply these new fixes. Microsoft has created the Qchain tool to chain hotfixes together in order for only one reboot to be required when installing several fixes.
