Modem won't release IP given from ISP

Hello,

I have a Dell Inspiron 8100 laptop w/ an integrated LT Win Modem. Every time I dial up to my local ISP when I'm traveling to check my work email I get the same IP address. I'm not able to get onto the Internet because the address that the modem is using is not valid. I should get a new address from the ISP every time I make a connection.

I have updated the SP on my Office 2000 installation, uninstalled IP and reinstalled IP, uninstalled and reinstalled my modem and nic, deleted all dial up connections and created new ones, installed Win2k SP2.

My isp is not using DHCP so the release command w/in ipconfig does not work.

Can someone help?

Thanks,
Katie Logan

It's not an issue of the modem (per se). The modem does not store and/or release an IP address. The IP address is part of the TCP/IP configuration for your dial-up connection.
Make sure the TCP/IP properties for your dial-up connection are set to"Obtain an IP address automatically". If you have a fixed IP address assigned, your ISP has no way of giving you a new one automatically. Even though your ISP may not be formally using DHCP, their Remote Access Services (RAS) Server provides an IPaddress from an assigned pool in the same manner as a DHCP server. If you still can't connect after checking this, the issue could be with your ISP's RAS server (assuming you are successfully connecting to that server).
Hope this helps clear things up a little.

My ISP assures me that it is my problem. The ISP has several different access numbers, based on different towns w/in the state. Each town associated w/ a different pool of addresses from the RAS servers. I have called those other access numbers and still get the same IP address. I don't have another ISP that I have an account w/ to see if that changes the problem.
