    Every computer hooked up to my home network seems to have this "problem"

    When the computer is idle or not the network usage is always at 0.01% and my hard drive light blinks on and off every second or so. It doesn't affect performance that I can see but it does bother me that something is constantly writing to my hard drive is there some service or something that is causing this?

    It may just be background activity or inaccurate reporting of the state of your network card ;)

    To see whats going across the wire use a packet sniffer such as PMON from analogx.

    To check what process or processes are writing to disk why not monitor them using task manager. On the processes tab set the option to monitor I/O Writes Bytes.

    Well background disk activity on a 2000 or XP system may not be too unusual, especially with XP as it likes to index and re-arange file.

    For the network again a few things come to mind but you will soon spot whats going on with a packet capture if its a chatty system or protocol (or background traffic).

    Save the trace and e-mail it to me, ill take a peek.

    Use "active ports" to see what process is holding port 2869 open and that will give us some indication of that it is.

    Networks blink all the time. What you see are probably broadcast packages of different kinds.
    - Windows checkin the netowork for nearby computers.
    - DHCP broadcasts
    - Router broadcasts

    Any ICQ or similar will also send packets from time to time.

    the computer that the info came from has nothing like ICQ or AIM installed or even running.

    From PMON use File Save As and then e-mail the saved file.

    It may be the "alerter service", still checking.

    Krux, do you use internet connection sharing or the XP Firewall?

    2869 is used by ICS/ICF (ALG service)

    Classically it has also been suggested the following services play a hand:

    SSDP Discovery (Should be disabled)
    Upnp (Should be disabled)
    Alerter (Should be set to manual)

    I couldn't find upnp on the service list, was that a typo or is it hidden or something?

    Those addresses look like your router and some of your network computers chatting.

    Port 2869 looks familiar... Something I installed recently. Damn can't remember.

    Well when i unplugged my liteon drive the blinking stopped.....used the reg edit after pluging the cdrw back in and it too stopped the blinking led.

    This topic has been well covered in the shuttle forums in the past...its not a liteon thing either.
