Hi, I have disabled SSDP in controlpanel->services->SSDP Detection Service on one of the machines (192.168.2.10) - But i am still seeing the same ticking effect same as on the host that doesn't have this service disabled. Again I am lost with no clue, Any ideas?
Thanks again

Mark

Just disable the ssdp service on the Windows XP and it will stop the
discovery process. UPNP is the new Universal plug and play feature (thanks
again M$) that try to discover new hardware on the LAN. For more information
on this subject you can get an eye on http://grc.com/unpnp/unpnp.htm
