OS WinXPpro, sp3, nearly all updates.

When my 1Gb emachine is connected to the net, via internet connection sharing,
it gets sluggish and shows processor activity of 1-2% constantly. As soon as
the net connection is broken the traffic stops.
I downloaded Process Monitor from www.SysInternals.com and whatever it is
appears to be using UDP and TCP both SENDing and RECEIVing
intensively with over 260 communications in 66secs nearly all of which are as
in the topic description
computername.mshome.net:1087->192.168.0.1:2869

Other data common to most of these comms is PID 912 svchost.exe which is
the one with nearly all the services running on it.
The repeating element is one SEND followed by two RECEIVE with lengths
740, 204, 958.

Does anyone have any idea what is going on here? I will be very grateful for
any assistance or advice to get this sorted out.

Seems normal. Do you have any firewall running?

The chemist:

I'll try to explain...

computername.mshome.net:1087->192.168.0.1:2869

You have your computer set up in a network and it is a shared connection.

The name of the net work (by default) Mshome

192.168.0.1 is your IP address used by your router(do you have a wireless network in use?)

the other number is a port Id

The svchost.exe process that is running all the processes is the main process in Windows. It replicates it self as needed to provide system stability.

Like Dragonmaster Jay said everything looks normal.

I hope this helps

Good luck, and reply back if you need anymore assistance

Hi Dragonmaster Jay and Cbarnard.
Many thanks for your interest in this.
I'm using the standard windows firewall.
The LAN workgroup is WORKGROUP, so there's no reason for MSHOME to appear anywhere.
Otherwise, yes, as you say, everything looks normal.
Except, as soon as the internet connection is made, that particular computer gets and stays
busy, to the tune of about 2% processor time. This may not sound significant, but compared
to when it's idle it becomes a right dog (no disrespect to dogs), with delays before everything.

I'm sure there's a process which is started by the internet connection, or one which gets busy
when that connection is made, which shouldn't be running. The main thing about the MSHOME
link is I have nothing which uses that label for anything.
The other PC's on the network drop back to 0% processor activity after an initial flurry of
excitement at being joined with all those other PC's. The others are desktops too (2G Dell and
a 2x3G HP) but this one still has remnants from the last person who had it. It's clean (to Avast
Superantispyware and Spywareblaster but I wondered about old lmhosts files and the like
which could be looking for old friends of previous users. It is a trusted source, which is why
I didn't format the whole thing and start from scratch, but I only recently set up the ICS and
put it on the net.

Thanks again for your help with this.

Looks like you are missing some network components.

Please reinstall the network drivers on the computer which has the problem.


If this does not resolve the problem, then remove the drivers for the network card first by uninstall and restart the computer -- then try to reinstall the network drivers.
