Hi, after reboot, when any program attempts to connect to the internet the svchost.exe (NETWORK SERVICE), which runs DNSCACHE, uses 99% Cpu for about 5 mins. Currently I have disabled DNSCache and the problem is gone, but I googled and discovered that this can cause me to use more data than normal.

I was wondering if there is any way to resolve this problem.

My computer has recently been freshly reinstalled. I run win xp home sp3. I have scanned for malware and viruses and updated all programs.

Is it possible this problem is related to my hosts file? Or to my wireless cards drivers?

The only solution I could find through google was 3 years old, and I was unable to follow it because it required me to install obsolete windows updates.

Thanks in advance for your help.

Please remember that your XP is a lot older than 3 years. Some of these ideas are still OK to use on all XP units.
If you reinstalled XP SP3, then you will usually need to reinstall all the security and some other updates that may be missing.

No I was unable to follow it because you cannot install older updates over newer ones. My XP is completely up to date.
