Using a Sony Laptop, Windows XP home, Linksys Router, Cable Modem
I had the problem in the past of Svchost - DNSCache using up to 96 to 98 percent of cpu, forcing a shutdown and reboot to clear it.
START | RUN | SERVICES.MSC
STOP AND DISABLE
It cleared the cpu usage problem, but the problem now is no internet connection after a certian amount of time that my system seems to decide on on its own, anywhere from 10 minutes to two or three hours. I can repair the network connection and it comes back as operation completed, but still no connection.
Restarted DNS client, set it back to automatic. Now don't have the cpu usage problem anymore.
Cleared my Hosts file for what its worth.
Using Log off and log on to clear network connection problem, even though im the only one using the laptop
