Hi, I'm running XP and use a shared wifi LAN thta I have excellent connectivity with. After I open IE and go to a few pages or conduct a few searches I consistently get the error: IE cannot display the webpage. (even google or msn.com) I generally can repair the problem by ipconfig /release & ipconfig /renew. Although doing this sometimes results in a error: unable to connect to your DHCP server, the connection is then immediately restored and I'm good to go for another few pages. Sometimes ipconfig /flushdns seems to fix the problem as well - but not always.
I do have OneCare and did have some malware. Is the problem lingering from malware? Is OneCare trying to reconfigure my (shared) router? Do you have a reliable solution?
