Trivial bug in IIS5 SSL

If you select "require secure channel" and "require 128-bit encryption"
under secure communications in IIS5, and then later deselect "require secure
channel", browsers will fail to connect with "page must be viewed with a
high-security web browser...HTTP 403.5 - Forbidden: SSL 128 required". This
even occurs with a 128 bit enabled browser (i used IE 5.00.2920.0000).

If you remove the check next to "require 128-bit encryption" (which is
greyed out when "require secure channel" is deselected), then you can access
the pages as normal. IIS is failing to ignore the 128 bit requirement when
SSL is turned off.
