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 compact disc into the %windir%\system32 
directory to restore it.
