netbios port 139 is usually listening.
the netbios service resolves microsoft/windows network names.
to close that port you could use a software firewall (bad), or much better a hardware firewall.
some software-/desktopfirewalls: zone alarm, norton firewall (former at-guard)...
to see which program/service is listening or using a port you can use netstat in a 'dos box'

have a nice day,

if you need the complete path try searching for files and folders.

You can delete Netbios (it's a protocol) from network properties if you don't use it (and be sure to delete Netbios over TCP/IP also)

Sorry, I misread your second post.  You should try to get a hardware firewall.
btw, what utility did you use to look for open ports, or have you tried something like this:
Shields Up: https://grc.com/x/ne.dll?bh0bkyd2

only you have to do is  just put thick disable netbios on TCP/IP in network communication/TCP-IP properties/Advanced/Wins.

Then why did you accept my comment as an answer? Especially with an "C" grade?

You should really check zonealarm, if it can block NETBIOS if you don't use it. The best solution still is a hardware firewall, but they're pretty expensive if you want a good one.

LucF you are right i am sorrry i had misread it. in 9x  it can't be easily disable the netbios as being NT, first you remove the  file and print sharing and than get a firewall (like zonealarm) and i also recommend the Kerio Personal firewall strongly. Sorry again for the misunderstanding.

Best Regards

 FYI re: hardware firewalls.

For the past 6 months I've been using an excellent privacy protector called Alpha Shield. It's plug 'n play and requires no configurating or updating. It sits between the modem and pc and blocks out all unrequested packets, keeping you in stealth mode while on the net. It cost $140 CDN but it's a small price to pay for peace of mind. (won't work with dial-up though) Along with NAV and Adaware I've had no probs.
