    Does anyone know how to setup an exchange server with Windows Small Business 2003 Server. I was told by my cable provider, "Cablevision of Long Island" needs to setup a Static IP address. Cablevision charges an additional $25 per month for the Static IP address! Is that correct or can this way be bypassed? My E-mail is already working on the exchange server!

    I'm assuming you're talking about setting up your own personal exchange server. If you've got your server set up behind a cable modem, then chances are the public IP changes every time DHCP issues a new address to your cable modem.

    The easiest way around this is to use a Dynamic DNS service. With a dynamic service, you get a DNS name and load a client on a PC on your network. It will periodically go out to the dynamic serice and update your DNS name with the correct address. That way, anything you point to your dns name always gets to your network without the need for a static public IP.

    Some firewall/routers support dynamic DNS natively and all you have to do is key in the login info from your dynamic DNS service and it will keep your IP updated.

    Unless your server is the only PC connected to your cable modem, you will also need to set up port forwarding on your firewall/router so that mail traffic that hits your firewall gets directed to your mail server.

    I use DYNdns because it's free.

    Good luck.

    You might want to monitor your server's ip address for a while and see how stable your ip really is because in my experience most cable broadbands change your ip very frequently (as opposed to most DSL connections). When I used to run my server on off a cable connection (3 different providers) I only had to update the DNS records once every 2-6 months when they happened to perform maintenance. The paperwork and reps will tell you it's not dedicated because it can change but is quite possibly infrequent enough it's not worth the extra money. It only really sucked if it happened to change when I was geographically distant from the server and couldn't update the DNS until I got back.
