I'm sorry if this is a bit of a basic question, but hear goes... I hope someone will advise me! Firstly, as you've guessed I'm no expert. I have just set up and been using the DNS, the purpose of which was to track the IP address of my non static IP address of my broadband so that I could remotely connect to a control unit. I set it up Friday (yesterday), it all worked fine (locally and remotely) on both Friday and Saturday, however this evening the connection is failing and I'm trying to workout what could be causing this. My specific question is because my dynDNS updater is on my laptop will it update the update domain with the IP address of the network the laptop is currently on? I do not have another pc so I will always be carrying around my laptop to different locations. I ask this because when I've connected remotely I've done so with an app on my iPhone. This no longer works, and the one thing that I've done (since it has stopped working) is go on line with my laptop at a different locations. This makes me wonder if the updater has updated the domain with the wrong ip address. Maybe I’m totally off base; any advise would be appreciated.

Yes, the update client has to run on the network you want to remotely access. If you run it on your laptop then it will update with the WAN IP of the network your laptop is on. What you need to do is ensure that your router is one with a [known working] built in client. You then need to disable the client in the laptop. : http://www.dyndnscommunity.com/questions/4163/update-clients-known-to-work-with-dyndnscom.html

In case you can't do it with the router, you may use Marc's Updater on your laptop. This allows to restrict updates to certain LANs (DHCP IP address) and/or WLANs (SSID).
Better than nothing, but it's a bad idea to use an Update Client on a roaming device. Beside that it updates with the wrong IP address when abroad, what you have experienced, it does not update with the right IP address at all when abroad and the ISP changes the IP address.
