I have a recent and urgent problem ... TILLIE has lost the ability to resolve names to IP addresses. That is, its browser (IE-7) cannot bring up my home page (or any home page). It just gives a message that IE-7 cannot display the page. In diagnosing the problem with a RoadRunner tech, I reset the link adapter (disable/enable), used 'ipconfig' to flush the DNS cache, and used 'netsh' to reset the winsock. Nothing would make TILLIE find Google or Yahoo by name, though it has no problem pinging addresses inside the LAN or even Google and Yahoo (by IP address NOT by name) out on the WAN. It appears that something is forcing the use of a DNS server and that Internet Explorer's calls for the 'home' page are being redirected to somewhere else.
This problem has been on-going with TILLIE for several days now, and just yesterday the same problem appeared on the laptop (HORSE) but is not consistant (yet) on HORSE. I mean that HORSE seems to also have the 'bug'. It also loses Internet connectivity (apparently randomly) with the same symptoms. However, unlike TILLIE which seems to be permanently out to lunch, HORSE can be powered off for a long while and when powered up again behaves properly (for awhile).
I would like to address the TILLIE problem in this forum, and get help cleaning out whatever is causing the problem. This sounds like a trojan or virus to me (the RoadRunner tech gave up after the winsock reset failed to fix the problem) not a LAN configuration problem.
Since TILLIE cannot connect to the Internet, I cannot download Malwarebytes and other programs directly ... but I can 'sneaker-net' it over on a flash-drive. Likewise, posting the results back on Bleeping Computer might be cumbersom, but if I can get whatever programs I need to use to write their output to a file on a flash drive I can upload it from another computer.
Thanks in advance for considering this problem.
