You're information won't get forwarded becuase it's wrong. The ATT network uses true DHCP, if you set your IP static you will not get online for any longer than a day. Manually setting the DNS servers is also a temp fix. XP and Win2k has a service called "DNS Client" that affects the way your system performs a DNS search. Here's the fix: Open control panel, go to Administrative Tools, open Computer Managment, click Services and Applications, clickServices, double click DNS Client: change startup type to manual, and change service status to stop.
