Recently encountered a difficult problem on my win2000 machine w/ SBC DSL 5100speedstream & Network everywhere router. DHCP, automatic IPs.
I installed some recent windows updates (2 misc win patches, IE patch) and restarted. After reboot, I had no Internet access, but could still access my other machine on network .
After diagnostic attempts with SBC, I found I was unable to complete any pings, could not communicate with the modem, and dhcp IP number settings shown in IPconfig had changed. I suspect some kind of software problem occured with the DHCP server in Windows, but this is relatively unfamiliar territory for me. I've checked all configuration settings I could find.
If you can provide me with any insight and/or need more information, I would greatly appreciate your time!
Thanks for reading; Kevin
