Don't use File and Print Sharing if you don't need it. You can check if it's turned on in "Control Panel > Network > File and Print Sharing". If you have a LAN and need to share files, follow the guidelines below:

• Unbind File and Print Sharing and Client for MS Networks from TCP/IP - you will need to check all TCP/IP Entries in "Control Panel> Network".
• Install NetBEUI and bind File and Print Sharing to it.
• Turn access on just for the necessary directories/drives and make it read-only.
• Use strong passwords -- using alpha & numeric characters-- for all your shares.
