netbios

[Goeman Stefan <Stefan.Goeman@siemens.atea.be>]

Hello,

When I do an nmap on my pc, I get something like:

Port    State     Protocol   Service
.....................................
..... some services .................
.....................................
139     open        tcp      netbios-ssn


I am a little concerned about this last line.
>From a security course I took last week, I have found out
that it is not wise to have the netbios open (to the rest of the
world). I my case, it probably can't harm because I am behind our
company firewalls. But nevertheless, I would prefer to disable this 
feature. Does anybody knows how to do this ??


Greetings,

Stefan Goeman
