[Help] Is there some way to disable DNS in XP? in Networks and the Internet Posted February 2, 2007 Hmm, I do have one idea that might stop itHave you tried opening a command prompt and performing a ping of say www.google.com, if that works then it's the Internet browsers that are flakey if it doesn't (and you can ping google from a working machine) then the prob is lower than that. Also try a ping of 66.289.89.99 (Googles IP) those results will also give some info as well, i.e determining whether it's simply a DNS fault or the whole thing is having troubleIf pinging Google works then have a look in the Internet browser and see whether the proxy has been changedFirefox is Tools - Options - Advanced - NetworkIE is Tools - Internet Options - Connections - LAN SettingsIf you're not sure what they're meant to be, just jump to another PC on the same network and compare@cluberti, Its not the hosts file. I've checked that. Deman,I checked the proxy and no, its not been changed. All normal connection specific things that are readily apparent are at their default states. Whatever it is, its preventing the PC from getting/seeing the DNS server addresses. Disabling the connection and then re-enabling it, or the physical unplugging and plugging back in of the ethernet cable does not change anything. The PC gets its LAN IP address readily, but not the DNS addresses.I do not want to tell her that one way would be to re-install Windows, because the vendor did not leave the CD of the OS nor the surveillance application CD for her.
