Switching ISPs and SMTP settings on Exchange Server 2000

I have a server that's been set up on Exchange on Windows Server 2000. We are switching ISPs tomorrow (still have a static IP, but are switching from DSL to Cable) and I need to make sure that the SMTP settings in the server are correct (and any other settings?) so that it does not lose or stop sending/receiving mail. Do you have suggestions on how to change these settings? I am not familiar with changing the settings in Exchange 2000. Thanks.

You need to change your DNS settings on what server? I would just change your forwarders on you current server to the DNS server's provided by the ISP.

You need to change your MX record to reflect the change also. Is your exchange server on your LAN with a private IP address with port 25 opened to the box? If it is, you will only need to make the change to your  MX record. I would do this at asap as you are changing tomorrow.

Hello, Right now I have the server behind a router and firewall; port 25 is forwarded through. I am also aware of chaning the MX record to reflect the new IP. My main question, though, is whether or not there are some type of settings regarding actually sending mail that I need to change within my server. How does it know where to "go" to send the mail out? I guess I was thinking that there would be something that I need to do in terms of SMTP server or something with the ISP. Perhaps I am totally lost and this is not necessary since the Exchange server would connect to the DNS server and locate those external mail servers of other parties and then just resolve and send the messages without help of the ISPs SMTP server. Is that more accurate? Sorry to be ignorant.

As long as the exchange server can resolve DNS queries it will send mail.

Let me rephrase that...

As long as the DNS server the Exchange server is using can resolve external host names you will be able to send mail.

Okay, thanks. It will be able to do that. On another note, I will need to change the DNS settings in my server. Is the only place that I have to do this on the DHCP settings? I know how to do that, but is there anywhere else?

On your current DNS server that it.

Right now the router (Linksys WRT54G) is connected to the modem (will also be connected to cable modem). The DNS points back to the server (the router hands out DHCP), so I am thinking that the ISP's DNS settings need to be in the server. Where do I go to change those?
