Reconfigure NetBIOS on Windows 98/ME

Follow these four easy steps to reconfigure your NetBIOS and protect your Windows system: Install the NetBEUI protocol Check whether NetBEUI Protocol is already installed: On the Windows task bar, click Start > Settings > Control Panel Double-click on the Network icon to open the Network window Click on the Configuration tab Scroll through the list of network components and verify NetBEUI is listed as an installed component If NetBEUI is already installed, go to step two: Configure Hardware Adapter. If not, install NetBEUI: Click Add on the Configuration tab in the Network window Select Protocol as the type of network component you want to install Click Add Select Microsoft as the Manufacturer in the Select Network Protocol window Select NetBEUI as the Network Protocol Click OK to install NetBEUI Click OK to close the Network window You may be asked to insert your original Windows CD. Configure Hardware Adapter On the Windows task bar, click Start > Settings > Control Panel Double-click on the Network icon to open the Network window Click on the Configuration tab Scroll through the list of network components to find all Hardware Adapter components. Select a Hardware Component from the list Click Properties Click on 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. To bind a component, check the box next to the component; to unbind a component, uncheck the box that appears next to the component.   Dial-Up Adapter users:   If you do not have a LAN adapter in addition to your dial-up adapter, leave TCP/IP and NetBEUI bound to Dial-Up adapter. Unbind all other components (e.g. IPX/SPX transport protocol). If you do have a LAN adapter, see LAN user sections.     Cable Modem or DSL users:   Bind Network Adapter (NIC) to TCP/IP and NetBEUI. Unbind all other components(e.g. IPX/SPX transport protocol)     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)     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) Configure Network Transport Protocols On the Windows task bar, click Start > Settings > Control Panel Double-click on the Network icon to open the Network window Click on the Configuration tab Scroll through the list of network components to find all the TCP/IP Protocols Select a TCP/IP Protocol from the list. Click Properties Click on the Bindings tab If a message box appears and warns you that it is better to set TCP/IP properties in each connection icon and that changing those of the adapter will override the per-connection settings, click OK. You do want to override all per-connection settings. Uncheck, or unbind all network components listed Click OK to close the TCP/IP Properties window Repeat steps 4 - 10 for each TCP/IP Protocol installed Click OK to close the Network window Re-Boot Your Computer System Your computer must be re-booted for the reconfiguration to take effect. After re-booting, NetBIOS will be configured for maximum security. Special Note for Comcast Users If you find that you cannot connect to the Internet after editing the TCP/IP Properties: On the Windows task bar, click Start > Settings > Control Panel Double-click on the Network icon to open the Network window Click on the Configuration tab Select your TCP/IP Protocol from the list Click Properties Click on the Bindings tab Re-check, or re-bind the Client for Microsoft Networks Re-boot your computer WARNING! Even after you've made this modification, you will not be completely secure against NetBIOS attacks. To be safe, you'll need to install and configure a firewall to block attacks against port 139, but to allow access to port 137 and port 138. Configuration instructions for Windows XP
