SYMPTOMS
On a Microsoft Windows 2000-based computer, the Lsass.exe process may use too much CPU time if both of the following conditions are true:
 * Internet Information Services (IIS) 5.0 is installed on the computer.
 * Secure Sockets Layer (SSL) connections are enabled on the computer.



CAUSE
This problem may occur if an IIS 5.0 Web site is configured for certificate mapping, and a client requests information that requires client authentication while SSL is enabled.
