I had recently moved from a usb modem to an ethernet modem and was empowered to use my LynkSys as my Dynamic DNS updater.  After a couple of months, however, I received an email stating that I was being blocked due to update abuse.  I asked for more info regarding the situation and the DynDns support rep was happy to reply and inform me that my router was updating on a timer, which is not allowed.  Unfortunately, three days later, I received another email stating that my DynDns account had been removed due to continued abuse.  The service they provide for free is absolutely fantastic and I certainly cannot complain that they have no patience for slackers who fail to fix their problems immediately.  So I finally spent about an hour getting things straight tonight.  I've disabled my LinkSys and returned to using the DynDns updater.  I was pleasantly surprised to find it now runs as a windows service!

If you're not famliar with Dynamic DNS and what DynDns provices, it allows you to point a url at your home computer that will allow you to access it from anywhere in the world as long as your computer tells the dns host what your ip address is every time it changes.  Simple but very powerful.  By installing a beacon service on your computer, you keep the DynDns server informed as to the address of your computer.  All requests are proxied through their server to allow access to your computer.  When your ISP changes your ip address, the beacon tells the DynDns server about the change.  You should never have to worry about it.  However, reboots can get tricky.  When I had a usb modem and the computer rebooted, my url would no longer connect to my computer until I physically logged in and established a connection.  I was very happy when I could use my router to update the server.  Too bad its an abusive piece of ...equipment.

To get a dyn dns account, go here: https://www.dyndns.com

create an account, then add a host to dynamic dns.  It will detect your ip address right there.  I won't go into detail about setting up wireless routers and port forwarding.  You can tackle that elsewhere.

Now download and install the preferred client: DynDns Updating Client

Set up an account that points to the domain you set up on DynDns.com. 

Once it is updating and the icon turns green, go to options on the dynDns client properties window, deselect "start with windows"  and click "install service"

Then exit the client by right clicking and selecting "exit"

Go to control panel > administrative tools > Services

Find "DynDNS Updater Service" right click and chools "start"

Leave a comment if you could use more information or some screen shots.  I'll add them.  I just wanted to illustrate how easy it is to set up remote access to your home or office computer if you don't have static ip addresses to work with.
