  • OWA not working on Dyndns.org

    Hi
    I have sbs2003. I have user account at dyndns.org thru which I get my updated ip address on which my adsl is connected to isp.

    I can access OWA if i use the syntax https://ipaddress/exchange where ipaddress is my updated office wan ip address.

    But I cannot get owa access if I use https://xxxxx.dyndns.org/exchange

    If did some trouble shooting and found out following. If I ping to xxxxx.dyndns.org , I get reply from my office wan ip address. But if I ping https://xxxxx.dyndns.org or even http://xxxxx.dyndns.org I get response fromsome other ip , may be of dyndns.org so I am unable access the OWA as I am not reaching my office wan ip.

    Pls help how can I get access of OWA from my office using syntax https://xxxxx.dyndns.org/exchange

    Regards
    Vishal

    what error do you get if when you try and browse to the dyndns hostname ?

    I would suspect this is related to a host header - the way IIS is listening for the web url..

    for instance - iis is probably listening for 1.2.3.4 on port 443
    what that means is that even if the same srver has another ip address of 1.2.3.5 port 443, and you try and browse the site in that manner, it won't work, as it's only listening for 1.2.3.4:443
    Please do show your appreciation to those who assist you by leaving Rep Point https://www.petri.com/forums/core/im.../icon_beer.gif

      did you install the Dyndns updater? If you did, both pings should reply with the same IP adress.

      Also, what error do you get when browsing to http://xxx.dyndns.org? Your default website might be set up to only listen to requests for the IP adress, not for the domain name you added.

        Have you opened port 443 and forwarded it to your exchange server?
