hey all, quick question, i was messing around with netstat and nmap just seeing what i could find on my college network, well i did a "netstat -a" command and noticed this

tcp mycomp:3864 lacompto.mycollege.edu:netbios-ssn time_wait
tcp mycomp:3868 lacompto.mycollege.edu:netbios-ssn established

(i changed the DNS for obvious reasons)
is someone connected to my computer using netbios? or is this just the result of someone attempting to scan for ports on my computer when i asked for a netstat report.

i thought you could only connect to netbios on port 139.

i have a firewall running and i have disabled file/print sharing and im fairly sure i have disable the netbios service...how is this possible? any/all advice is appreciated.
