I'm trying to publish OWA 2007 with ISA 2006, and I'm getting a problem with the certificates. OWA works fine internally, and when I try to access it through ISA I'm able to authenticate, but after that step I get the following error message:
Error Code: 500 Internal Server Error. The certificate chain was issued by an authority that is not trusted. (-2146893019)
I followed the instructions in this site to publish OWA,
but I imagine I failed exactly where the site fails to develop, in the CA authority configuration. I installed one CA authority on my DC and Ive been able since then to issue and request certificates.
But for some reason this is failing. Since I'm not very familiar with this area maybe you might help me.
