  • Microsoft Windows NT Server version 4.0

Notes for Users of the 128-bit North American version of Windows NT

All encryption related components in the version of Service Pack 2 are limited to exportable 40-bit cryptography. During installation, you will be prompted when an existing component on your system, containing 128-bit encryption, is about to be replaced by an updated component with 40-bit encryption. If you require 128-bit support, you should click the "Skip" button on the dialog box when prompted during Service Pack Setup. A version of this Service Pack with 128-bit encryption is available on request. See ordering information below.

Microsoft Internet Explorer supports both 40-bit and 128-bit encryption depending on the version (40-bit or 128-bit) of the file Schannel.dll. If you accidentally overwrite the 128-bit version of Schannel.dll with the 40-bit version included in this Service Pack, you can copy the original from your Windows NT version 4.0 CD into the %WinDir%\System32 directory to restore it.
