Configure NetBIOS 95/98/ME for Maximum Security.

·        In Select Network Component Type dialog box, choose Protocol, then click Add

·        In the Select Network Protocol dialog box, choose Microsoft from the Manufacturer's window

·        The Network Protocols for Microsoft will be automatically displayed in the right hand window, under Network Protocols

·        Scroll through the list to find NetBEUI, click on it once

·        Click OK button. Hint: If the computer cannot find the necessary files for NetBEUI installation on your hard drive, you may have to insert your original Window OS CD-ROM.

2. Configure Hardware Adapter

·        In the Network dialog box, choose Configuration tab

·        Scroll down the list of installed network components to find all Hardware Adapter components. Hint: Hardware Adapters are denoted by a circuit board item like this:

·        Depending on your Internet connection, your list of Hardware Adapters may include "Dial-Up Adapter" for dial-up service or "NIC" for Cable and DSL service. Or, the list may include both components.

·        Click on the Hardware Adapter component, then click the Properties button at the bottom of the list

·        In the Properties dialog box, select the Bindings tab

Hardware Adapter components are configured differently depending on your Internet connection. Find the applicable user group below, to configure each Hardware Adapter component. Hint: To bind a component, check the box next to the component; to unbind a component, uncheck the box that appears next to the component.

For Dial-Up Adapter users:

·        If you do not also have a LAN adapter (if you do have a LAN adapter, see LAN user section below), leave TCP/IP and NetBEUI bound to Dial-Up adapter, unbind all other components (e.g. IPX/SPX transport protocol)

For Cable Modem or DSL users:

·        Bind Network Adapter (NIC) to TCP/IP and NetBEUI, unbind all other components (e.g. IPX/SPX transport protocol)

For LAN users who want to give all connected computers Internet access:

·        Bind Network Adapter (NIC) to TCP/IP and NetBEUI, unbind all other components(e.g. IPX/SPX transport protocol)

For LAN users who DO NOT want to give all computers Internet access (e.g. if you have young children):

·        Bind Network Adapter to NetBEUI ONLY, unbind TCP/IP and any other components (e.g. IPX/SPX transport protocol)

3. Configure Network Transport Protocols

·        In the Network dialog box, choose Configuration

·        Scroll down the list to find the Protocols. Hint: Protocols are denoted by an icon like this:

·        Click on a TCP/IP Protocol (there will be more than one, you must configure each TCP/IP Protocol separately), and click Properties button at the bottom of the list

·        Select the Bindings tab in the Properties dialog box

·        If an information dialog box appears, that tells you that you want to edit the TCP/IP Properties for each connection, instead these properties, which apply to all dial-up connections, just click OK. You do want to change all network service bindings properties.

·        In the list of Network Service Components, uncheck, or unbind, ALL components. If you have multiple TCP/IP Protocols (e.g. for dial-up and networking), be sure to unbind components in each protocol

·        This final step will ensure that the infamous port 139, which exposes information from your computer to the Internet and hackers, is closed

·        Double check to be sure that all network services are unchecked, or unbound, for each TCP/IP protocol. If there are any instances of binding between network services and TCP/IP protocols, all security holes remain open.

4. Re-Boot Your Computer System

Congratulations! Your NetBIOS are now configured for maximum security. Your important data previously exposed through NetBIOS will be safe from hackers.

Special Note for @Home Users:

If you find that you cannot connect to the Internet after editing the TCP/IP Properties:

·        Go back into the TCP/IP Protocol through the Configuration tab in the Network dialog box (available through your Control Panel)

·        Highlight the TCP/IP Protocol and click Properties, then select the Binding tab

·        Re-check, or re-bind, the Client for Microsoft Networks box

·        WARNING! You will not be safe from NetBIOS attacks once you've made this modification. You will need to install and configure a firewall to block attacks against port 139, but to allow access to port 137 and port 138.

·        You will now be able to connect to the Internet via your @Home account
