Here is the problem we have:
We have a LAN of 5 computers and our server in connected to our ISP thru ADSL. The ISP gives our server a dynamic IP address. The rest of our LAN talks to the server using a static IP. We can log onto the Web but can't check our individual e-mail accounts from each station because of the dynamic IP address. Any way to get our LAN to recognize the dynamic IP? We are only able to obtain a max of 2 dynamic IP addresses from our ISP. Our so called 'tech' doesn't know what to do and we are stuck checking our mail thru a web browser instead of Outlook.

Your Outlook setup should have nothing to do with your addressing scheme. Outlook should be responding to the users login name and password as setup in outlook under services

What does your enviornment look like? Servers? Router? Just a quick insight, what you may want to do is setup your ADSL as the default gateway, and setup Windows 2000 server as a router or place a real router in your network. What you are facing is that the ISP is only giving you 2 IP address, what this means to you is that you cannot do much. You need some device that will give you Network Address Translation (NAT). Then you can tell it to resolve ip address and use your own IP scheme in your network, and use one IP address from your ISP as the default gateway.

Hope that makes sense.

if it was as simple as needing a static ip address for the server then all you'd need was a wins server. this would log the dynamic ip to the server name and supply it to the clients. and in fact if browsing and cahing is working for you the clients probably already get the reolution. try ping the server name and see if you get an ip back.
then all you really would need to do ( if it were that simple) was to point outlook to the servername rather than the ip.
but it isn't that simple.
you have been given an an ip from your isp which is acceptable to use in the outside world. your in-house ones aren't. the world musn't see them - they probably exist in many other places too!. the world must see only your servers ip and talk only to it. the server itself keeps track of which local pc sends and gets whatever. so you need a mailserver of some type to handle this. then the clients point to your server as the pop/smtp server and the server handles the rest for you.
there is a simple one on the resource kit
- check your mail.
