HELLO I have AT&T as internet provider. Normally Windows XP connects to internet with no configuration. BUT when I join to a domain, set the DNS IP in network connections TCP/IP properties I have Internet no more.

Is there any proxy settings for AT&T? Or should I modify something else after join them to windows server 2003 for having still internet?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. See the FAQ for guidance on how to improve it.

The first question is whether this is a DNS issue, or a connectivity issue. Try to ping 8.8.8.8 (a google dns server). If you get replies, it is just a DNS issue. Try to ping www.google.com. If you get replies, it is a probably a browser issue.

I could answer a lot more accurately with more information, but when you say domain, you do you mean being part of a Microsoft domain, right? If so, are you getting your IP config via DHCP, or is is static? When you are local to a Microsoft domain, the first DNS server MUST be one of your internal DNS servers on the domain, which will, in turn give you DNS records for external domains. Is this a domain you set up at home, or is this at work? Are you able to configure the domain's DNS server yourself?

Lastly, make sure that you have no proxy settings set in your browser.

Could you please post your ipconfig /all (feel free to sanitize the names), but keep the IP addresses, especially for the DNS servers.
