Hi there I'm wondering what this thing means? netbios-ssn there is this guy keeps connecting to my comp I found all about him, he lives 1 floor above 4 rooms down from me. now he's annoying me. i don't really know what netbios-ssn is, is he port scanning or something? or is he trying to send me some packets? or what should i be concerned, i haven't installed firewall, using xp sp2 firewall now.. Thanks ip: 66.71.50.145 he's connecting me at port 3803... edit: picture removed
