Microsoft encapsulates netbios information within TCP/Ip using ports 135-139. It is trivial for an attacker to issue the following command: nbtstat -A (your Ip address) from their windows machine and collect information about your windows machine (if you are not blocking traffic to port 137 at your borders).
