  • RPC - HTTPS client setup

    Hi All,

    I have been tasked with setting up RPC over HTTPS for my company. I have everything set up and it works well, except for configuring the client on our network. This does not work, they are prompted for their user name and password repeatedly. However, I can take the same laptop with the same setup to a drop that has connectivity on the outside of our network (Vendor) and it works fine. Once the acct has been set up once and has authenticated in, I can then put the laptop back on our corporate network and it still works. I believe that the issue could be certificate related, but I am unsure.

    Details:
    Front end / Back end
    FE - ports are configured correctly and certificate is valid
    BE - configured as per articles, however no certificate.

    Thanks for any suggestions and help.

    I am having the same problem...just backwards. I can not connect Outlook from outside the LAN.

    Password prompt is the farthest I can go. I am thinking that I have a port issue on my firewall....what ports are you having open to allow for the traffic to flow.

    I know that this wont help you situation, but maybe could shed some light on mine.

    Thanks,RC

      Port 443 (HTTPS) and Port 80 (HTTP) only
      You probably dont even need 80

              Do you have a split DNS system setup so that the external name resolves internally to the internal IP address?

                  Split DNS. http://www.google.com.au/search?sour...68&q=split+dns
                  1 1 was a racehorse.
                  2 2 was 1 2.
                  1 1 1 1 race 1 day,
                  2 2 1 1 2

                    Simon.

                    It was a split DNS issue. Once I corrected the forwarder it works fine.

                    Thanks!
