Thanx for the answer. Both my WinXP laptop (which will go back to Win2k or maybe RedHat) and my Win2k Pro workstation have started broadcasting these SSDP announcements. So it's not only XP and ME, but also Win2k. You, as me, have installed IE6 and MSN so this could probably be the reason for activating this UPnP bullshit (at least for now, not seen anything using UPnP). I will manually disable this feature thanks to James T. Moore's infomation. Hopefully my log will yet again containt none Local Lan entries. /Christopher
