Post-Windows NT 4.0 Service Pack 6a Security Rollup Package (SRP)

Microsoft has released a Security Rollup Package (SRP) for Windows NT 4.0 that includes the functionality from all security patches released for Windows NT 4.0 since the release of Windows NT 4.0 Service Pack 6a (SP6a). This small, comprehensive rollup of post-SP6a fixes provides an easier mechanism for managing the rollout of security fixes. Applying the SRP does not change the encryption level of your computer.

If you need to add optional services, follow these steps:

1. Install all optional services and companion services. You will be prompted for the original Window NT 4.0 media.
2. After the files are installed from the original media, but before you restart your computer, reinstall Windows NT 4.0 SP6a. You must reinstall SP6a before you reinstall the SRP because the SRP requires SP6a.
3. Restart your computer.
4. Reinstall the SRP.
5. Restart your computer.
6. Install other post-SP6a hotfixes as necessary. For more information about the SRP, visit the following Microsoft Web site:
