OPEN! The web is so insecure these days that new security "exploits" are being discovered almost daily. There are many known problems with Microsoft's Personal Web Server (PWS) and its Frontpage Extensions that many people run on their personal machines. So having port 80 "open" as it is here causes intruders to wonder how much information you might be willing to give away.

OPEN! As you probably know by now, the NetBIOS File Sharing port is the single largest security hole for networked Windows machines. The payoff from finding open Windows shares is so big that many scanners have been written just to find open ports like this one. Closing it should be a priority for you!

tas netbios qui tourne sur ta machine

tu peux aussi installer un firewall logiciel genre zonealarm ou tiny...
 
A+

en fait j'ai un routeur adsl qui fait petit firewall hardware, mais j'essaye de le configurer

Sous 2000 c' est désactiver Netbios dans les propriétés avancés des TCP / IP

en fait c'est bon c'est desactivé merci  
Preliminary Internet connection refused!  
This is extremely favorable for your system's overall Windows File and Printer Sharing security. Most Windows systems, with the Network Neighborhood installed, hold the NetBIOS port 139 wide open to solicit connections from all passing traffic. Either this system has closed this usually-open port, or some equipment or software such as a "firewall" is preventing external connection and has firmly closed the dangerous port 139 to all passersby. (Congratulations!)  
 Unable to connect with NetBIOS to your computer.
All attempts to get any information from your computer have FAILED. (This is very uncommon for a Windows networking-based PC.) Relative to vulnerabilities from Windows networking, this computer appears to be VERY SECURE since it is NOT exposing ANY of its internal NetBIOS networking protocol over the Internet.
