This has been defying my corrective actions for two days. This happened very suddenly. Whenever we use IE7 or any online function, we get a Comcast page saying we need to set our TCP/IP setting to “Obtain DNS server address automatically”. Our settings have always been that. We use SBS 2003 as DNS and DHCP, and have 7 PC’s XP Pro and the one server behind a switch, router, modem. I called Comcast, they said it looked fine from their point. I called Linksys (router), there was no problem, all settings are correct. I replaced the router and configured it as it had been, we briefly – two minutes – had internet, then it went back to the Comcast error page. Also, I can plug a laptop directly into the modem and have no problem getting internet. Also, if I take the network off the router and only connect one PC, it works fine. Thanks for any help!
