SYMPTOMS
Connecting to a Netscape server that requires client authentication may fail. After trying to connect, the server returns an "invalid certification" alert or just drops the socket connection.



CAUSE
Recent versions of the enrollment control (Xenroll.dll) place the intermediate certificates in the "CA" certificate store, rather than in the "MY" or "ROOT" stores like schannel expects (the "CA" store had not been invented when this schannel was written).



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
