Hi All,

I am trying to get my RPC over HTTPS working, but I am having a slight
issue with it. I configured a client on the LAN and connected up using
outlook.exe /rpcdiag. Over the LAN the client connected no problem and
the connection said HTTPS. When I try to configure a client to connect
from external the client times out when trying to communicate with our
server. I have ports 80 and 443 opened from the web to the Exchange
server and the traffic is making it there. The problem I am having is
with the authentication part of the process. When I open outlook it tries
to authenticate to our Exchange and opens an enter username and password
box. The traffic never makes it to the Exchange server. I see the request
bouncing off my firewall on port 135. I think this is due to a virtual
directory misconfiguration. I don't know why it is trying to authenticate
over this port. Any ideas? Outlook Web Access works perfectly over port
443.

Thanks,

Dave
