SYMPTOMS
Under certain circumstances, the Request object's ClientCertificate collection may contain information from the certificate installed on the server rather than information from the client's certificate.



CAUSE
This problem occurs when you have an old version of the Schannel.dll file on your system.



RESOLUTION
To resolve this problem, you must install the correct version of Schannel.dll on the Web server. The correct version of this DLL is included with the latest Windows NT 4.0 service pack.

STATUS
This problem was first corrected in Microsoft Windows NT 4.0 Service Pack 2.
