The problem is related to fragmentation of certain SSL packets. I.e. if the
call to receive() doesn't get the whole SSL packet (this can happen due to
various reasons) then IIS fails. I.e. someone very smart didn't know that
TCP is stream-oriented protocol... We had to do certain things to prevent
such situation. I must say that Java servers have the same problem.

If you want your certificate to be validated and SSL session to be
successfully established, then this is unlikely because the purpose of
client authentication is not just to verify the integrity certificate, but
to check the owner against some list (of people, allowed to use the

On the other hand, if you need just *some* SSL server, I can you can build
one easily with SecureBlackbox.NET (,
trial version will be enough. It supports client-side authentication.
