RE: Homeseer and Dyndns

["Wright, Ian" <iandwright@xxxxxxx>]

Thanks everyone

I was just being stupid.

It works fine now.  It is this port (80/81) thing that I need to boff up on
now.

It is so much easier

cheers

That kinda defeats the object!!

The whole point of dynamic DNS is to be able to do exactly that. The name
would/should be whatever name you >choose< to register beneath the
Dynamic
DNS service providers domain name, for example,
"www.ianshouse.dyndns.org"
then as long as you have a DDNS client that correctly updates your dynamic
registration(s) with that service (and does so promptly!), then resolvers
should be able to use that name to find your webserver.

The fact that when you go to the DDNS webpage and look up your IP address,
and find that is is correct and current, (as proved by the fact that
browsing to it gets to your HS webpage), proves that your client update is
occurring quite correctly...

I would then look at the configuration of the resolvers... Do you have a
cacheing DNS server between your resolver and the DynDNS server?

I have a very similar problem at the moment with some W2K workstations, - I
also use the DynDNS service, and a Dynamic DNS client to register my Home
webserver (NT4 server & IIS4), which redirects incoming HTTP requests
to my
internal Homeseer webserver. I find that the dynamic update portion works
perfectly, IE when my server's IP address changes, the client correctly
updates the dynamic registration, and does so very quickly. Checking the
DynDNS webpage therefore shows the correct IP address, just as in your
case.

However, I then find that some PC's on my internal LAN can ping the FQDN
correctly, while others cannot, due to resolving an incorrect (earlier) IP
address. My internal LAN also has a cacheing DNS server AND A proxy server
(also on the same NT4 & IIS4 box), and my internal clients use ONLY
these
internal services. My initial belief was that my internal DNS server was
caching the IP address for the FQDN from an earlier lookup, and issuing
that

to subsequent requests, - EVEN after the server had disconnected &
reconnected and obtained (and registered)a different IP. However, I've
looked in MY DNS servers' cache, and I cannot see it, so that doesn't
>seem<

to be the case...

I haven't got to the bottom of this yet, but I think I may have determined
that W2K clients and Win9X clients behave differently in how they perform
DNS queries,... I am still investigating, so I'll let you know if/when I
figure it out...

Anyone a Whizz on DNS care to chime in?....
