Security Problem: Your files can be shared all over the Internet

Problem: If your setup allows NetBIOS over TCP/IP, you have a security problem:

1. Your files can be shared all over the Internet.
Your logon-name, computer-name, and workgroup-name are visible to others.

Again, You face the same problem If your setup allows File and Printer Sharing over TCP/IP:

For Windows 95/98/2000 users: 

 1. The security problem can be solved by disabling NetBIOS over TCP/IP:
You must also disable the TCP/IP Bindings to Client for Microsoft Networks and File and Printer Sharing.

If, you still want to share your Files and Printer over the network, you must use the
NetBEUI protocol instead of the TCP/IP protocol. Make sure you have enabled it for your local network.
