Hi all- Have seen this posted quite a few times but no clearcut resolution.
I have upgraded all of our pcs to SP2 (WinXP). Since then only some of the
pc's exhibit issue. SVCHOST maxes at 100% for 5-10 minutes on bootup then
resumes normalcy.

I've narrowed it down to the Internet Connection Firewall causing the issue
(if I kill it the prob. goes away). I need to have this enabled. (Besides,
why is it only happening on some machines and not others?)

THINGS I HAVE DONE:
1. Run Spyware & Virus check (almost daily). McAfee and 2 different
anti-spyware apps.
2. Ran http://support.microsoft.com/?id=887742.
3. Checked unsigned device drivers (sigverif).
4. Affected pcs run different audio/video/sound cards (no consistency).
5. Disabled Application Layer Gateway service.

None of the above helped. Any ideas or suggestions as to what else I could
try? Any help at all would be greatly appreciated. Thanks in advance.

Is it the Windows Firewall or a third party Firewall?

Windows Firewall. Disabling it resolves the prob. However, we need to it
enabled.

You do not appear to have tracked down the Service / Application using
SVCHOST. The Windows Firewall blocks Inbound but not Outbound
connections so I would look for an application not getting a reply.

Task Manager is useful but you could look at another freeware utility
Process Explorer, which provides similar information but adds that
little bit extra towards seeing what the running processes represent.

For further information about Process Explorer see here:

http://www.sysinternals.com/ntw2k/freeware/procexp.shtm...

To ascertain which service is causing the
problem select the svchost producing the high CPU usage, right click,
select Properties, Services. Note there are the full names and some
explanation of what each service does.

You will find further information on Services here:
http://www.blackviper.com/WinXP/servicecfg.htm

To trace the particular Service involved you need to turn off each
service in turn and then restore it noting what effect it has on CPU
usage. However, you need to take care and watch what other Services are
dependent on that service. When you click on the Dependencies tab allow
it a little time to display the information.

I've got a similar problem as DavisSon. Using Process Explorer I've found
that an instance of svchost.exe with only the Dnscache service is consuming
my CPU. If I kill the process then the problem goes away. However, this may
make other apps like Explorer do funny things, like take me off line
constantly. Anyone know how I can repair the Dnscache service?

John,

This behavior is normal if you have a huge HOSTS file.
