Programs and services that use Secure Socket Layer (SSL) or Security Support Provider Interface (SSPI) may not function when Internet Explorer 5.01 is installed.


This behavior occurs because the released version of Internet Explorer 5.01 contains a version of the Schannel.dll file with an incorrect internal key.


To resolve this issue, apply Security Update, May 16, 2001 to install a version of the Schannel.dll file with the correct key. You can download Security Update from the following Microsoft Web site:


Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.


After you install a certificate in Internet Information Server (IIS) to allow secure access, connection attempts using Hypertext Transfer Protocol (HTTP) are unsuccessful and the following error message may be displayed:

The server returned an invalid or unrecognized response

Internet Explorer 5.x

Cannot find server or DNS Error

The following file is updated by Q247367.exe:

   File name     Size     Date         Version         Platform
   Schannel.dll  154,896  12/03/1999   4.86.1959.1877  x86

Microsoft Windows NT 4.0 Service Pack 6a 128-bit encryption is not affected by this behavior because it includes a copy of the Schannel.dll file, which contains the correct key and is a later version (4.87.1959.1877).
