Hi,

Following on to a similar thread by Massimo ponte, I also have a continuous
stream of LAN activity between my two networked XP Pro machines. Only
started happening recently as well. I have run all sorts of checks including
NAV, adaware, spybot, The cleaner, various online scanners etc etc but
nothing but the usual tracking cookies has been found. I'm fully up to date
with patches etc. Also my client PC's shared Internet connection is
distinctly faster than the host, is this normal? On the host pc (BT 512k
broadband connection) I can really notice a lag in opening websites,
downloading email, newsgroup headers and programs. The client Pc that is
sharing this connection is lightning fast. Any ideas?

Rob,

Do you have any software firewall on either (hopefully both) computers? If so,
does it give you a log describing what traffic is being detected by each
computer?

If not, get a port monitor like Port Explorer (free) from
<http://www.diamondcs.com.au/portexplorer/index.php?page=home>. Install it on
both computers, and find out for sure what processes are generating the LAN
activity. Once you identify a suspicious process, get Port Explorer (free) from
<http://www.sysinternals.com/ntw2k/freeware/procexp.shtml>. Provides way more
information than Task Manager.

Cheers,
Chuck
Paranoia comes from experience - and is not necessarily a bad thing.

Hi Chuck,

I have NIS2003 on host pc. Nothing but NAV2003 on client. Didn't think I
needed a second firewall on the client. I'll try the Port Explorer see what
it finds.

Follow up....

Installed Port Explorer (on both PC's) has been on for over an hour now. LAN
traffic isn't constant and hasn't been since install of Port Explorer (which
required a reboot). Whatever was causing it before hasn't reappeared, not
yet anyway. If it does i'll see what Port Explorer reveals and repost.

Cheers

Rob
