Hi
We have a small office and we are attempting to setup Exchange. Our ISP provides us with dynamic IP.

We registered for a domain with dyndns (elorean.homeip.net) and setup the router to auto update the IP and forward port 25 to machine with exchange.

This is where we hit dead end. I've set up local domain on Server 2003(scholes.local) and installed exchange on top of it. We're unable to send or recieve email and would appretiate if anyone can point us in the right direction.

I believe the problem lies in our DNS mess. Do i need to somehow connect elorean.homeip.net to our local domain on which exchange sits.

Here is a screenshot of the DNS screen
http://elorean.com/serv.jpg
The server with exchange is 192.168.1.105

i've also registered for Mailhop Relay from dyndns in hopes it would fix the problem, but no luck.

Thanks alot

This is what iam trying to do will keep you updated on my progress.

I have a win 2003 server ent and a linksys 300n router. i used dyndsn.org as it was suggested by linksys.

check list.

is the domain name on the server, the same as the one you registered with
DYNDNS e.g. yourdnslink.co.uk (domain registered)and
server.yourdnslink.co.uk
FQDN of server)
domain in server list yourdnslink.co.uk

Right click my computer and propertise, computer name and check here.

also is you server static IP'ed which you done by taking an IP address from you DHCP range on you router? this gives you a static IP for your server from a range already excisting on your router, also is you ISP IP static? check price as i might be cheap enough to purchase. mine is i paid ?5 to bulldog

is you domain name with dyndns as your dns records are held be another domain name registrar and makes things a little complicated as dyndns have to contact them and get the dns records to add to there dns servers. just a few thing to think about.

I installed server with all dns setting e.g. NS, SOA, MX, etc all fine. exchange works fine internally (have you check OWA internally
(http://your exch server ip address or domain name/exchange and have you configured all your outlook 2003 with exchange account for testing)

I setup an account with dyndns with custom dns, mailhop relay and domain name registration, making sure all thing link back to dyndns and there dns servers. got mine confirmation email yeasterday so i know there dns servers and doing there job but on my end something is missing and i am stuck like you.

i know the router setting need to be configured for port-forwarding to port 25 as as this links any request coming into the DG and then gets redirects to the IP and Port as specified.

ISP DG = 80.130.5.20
Srver = 192.168.10.10
DG = 80.130.5.20
router forwarding = 192.168.10.10 port 25
tick box next to option to confirm

i hope this help keep me post and i'll do the same

Putting another MX record to point to 192.168.1.105 or what ever the exchange server's ip is.

Just a thought.

download the client utility from dyndns.org and use that.

see FAQ on dyndns.org web site for their recommendations, which is to not use the router's DDNS utility.

I managed to get is all sort. Needed to contact my ISP and inform them of my ip for exchange server.

Thank everyone for there help and understanding. That reply was a bit crazy with the spelling lol. On the fly typing and rushing into meeting and crazy deadines don?t help but that's the price of IT for you.

P.S. always use word for spell checking.
