2 Way SSL Certification Setup (IIS 6)

[schroednic]

Hi all;

I am trying to setup a 2 way HOST-to-HOST SSL certification, or something of the like.
It's not really the same old Server -> Client ssl cert setup, I think?

I have my SSL certs installed on the server and the hierarchy with the provider (verisign/GoDaddy) is working.
We wish to send to my vendor my certs for them to install and conversely have them send their certs to us to install on IIS and have a 2 way trust.

Hopefully that can be setup. Thanks in advance.
