STATUS
======

Microsoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT
Server 4.0, Terminal Server Edition.

This problem was first corrected in Windows NT Server 4.0 Service Pack 6 and
Windows NT Server 4.0, Terminal Server Edition Service Pack 6.

MORE INFORMATION
================

To support FIPS 140-1 technology with Microsoft Windows NT 4.0, secure channel
support provided by the Secure Channel file (Schannel.dll) must be updated to
use 56-bit algorithms and the Microsoft Base RSA Cryptographic Provider in
Rsabase.dll for all cryptographic operations. Windows NT 4.0 Service Pack 6
contains the updated Schannel.dll file so that Windows NT 4.0 can support a
FIPS-compliant Web browser and Web server.

The Schannel.dll file is a system file located (by default) in
%SystemRoot%\System32 folder and is not displayed (by default). You can view the
Schannel.dll file in Windows NT Explorer (on the B menu, click Options, and then
click Show All Files).
