SYMPTOMS
If you set the PasswordChangeFlags value to 4 or higher, and the number of days that a user's password will expire is less than the PasswordExpirePrenotifyDays value, an Access Violation error message occurs.
CAUSE
If the PasswordChangeFlags value is set to 4 or higher, when IIS checks to see if it needs to redirect the client to the password expire page, the function IIS calls returns NULL instead of a pointer to a string containing the URL. IIS incorrectly attempts to use the pointer to check the string to see if it is empty without first checking to see if it has a valid pointer.
