ICS + svchost.exe

Hey,

I'm having some troubles with a XP SP2 PC, which acts as an internet
gateway by sharing its broadband internet connection (using a USB ADSL
dongle).

The problem is that whenever I enable or disable ICS (un/checking 'allow
other people to use this internet connection), or try to go to the port
mapping dialog (either from the PC itself or by clicking 'properties'
from another XP PC which has found the internet connection and popped it
into their own network connections list), svchost.exe on the gateway
computer takes up 99% of the CPU for about 5 minutes, before continuing
as normal. In this time, the computer is obviously very sluggish and
it's difficult to do anything at all.

Anyone know what's causing this or how to fix it?

Give up the idea of using ICS !

If you have DSL then you should get a Cable/DSL Router such as the Linksys BEFSR41. There
are many benefits to using such a device, including, but no limited to...
reducing PC overhead
offloading PPPoE to Router
Simplistic FireWall (Some Router models have full FireWall capabilities)
DHCP server
10/100 Mbps Ethernet switch

Such a device will help protect your PCs from hackers and internet worms. Since SVCHOST
(and variations upon that name) is the target of numerous infectors and malware, you may
already be infected by viruses or parasites.

Please go to one or more of the below online scanners and perform a scan of your platform
then report back your results.

Dave,

Yeah, I understand the benefits of a router, but unfortunately buying
one is out of the question this time!

The PC already runs AntiVir and is scanned each morning and updated with
the latest virus definitions weekly. It's clean from what I can tell.

AntiVir is NOT a top rated AV. Even top rated AV packages can miss infectors. Why do you
think I stated "...one or more of the below online scanners.." ? One might catch what
another misses.

There are False Positive and False Negatives. Just because AntiVir is on the PC does NOT
mean you are not infected. You won't know for sure UNLESS you try another scanner. Hence
my stating "...one or more of the below online scanners ...". Just the same they are AV
scanners, not parasitic malware scanners such as Ad-Aware.

As for buying a Router. It is NOT "...out of the question this time!" You just to run a
SOHO LAN cheap. You can be cheap, you can not take my advice but...you will be the price
later.

You asked for help, I gave you help & advice.
