You selected Mixed Mode authentication, but did not provide a strong password.

   
User Action

Mixed Mode authentication requires that you enter a strong sa password before you can continue to the next page of the Installation Wizard. A strong password must contain six or more characters, including at least one from three of the following categories: uppercase letters, lowercase letters, numbers, and non-alphanumeric characters (such as #, %, or ^). A strong password cannot be a reserved keyword, cannot include the computer name, and cannot include the username of the person logged onto the computer. For additional information on setting strong passwords, see the "Authentication Mode" topic in Books Online.
