SYMPTOMS

When you connect to a Web server by using a self-signed Server Certificate over a Secure Sockets Layer (SSL) connection, Microsoft Internet Explorer may generate an error message that states that the server could not be found, and Internet Explorer may then not be able to connect.

CAUSE

This problem can be caused if the Crypt32.dll file incorrectly determines that the server certificate is invalid. Additionally, this problem might also be caused if you have one of the following firewall programs installed on your computer:
  • Freedom Firewall
  • Zone Alarm by Zonelabs
  • McAffee VirusScan and Firewall
  • Norton Personal Firewall by Symantec
  • BlackICE PC Protection
