Troubleshooting techniques

What would be the hardware and software requirements for distributing an Internet connection (ISDN) through MAN (Metropolitan Area Network)? Is it advisable to use dialup net connection for smaller network (11 to 12 computers) for Internet surfing?

For smaller networks say about 6 to 7 users' dialup connection is useful. You can use a Proxy server to serve these users. With more number of users the connection tends to get very slow. In such a case it is better to go in for an ISDN connection.

Sharing an ISDN Connection through MAN: For sharing an ISDN connecting through MAN you need an ISDN Capable router (namely a Cisco 2503). The Cisco 2503 router has 1 Ethernet port, 2 serial ports and 1 ISDN BRI port. The ISDN BRI Port can be connected to the ISDN service and the Ethernet port of the device can be connected to the 10/100 Mbps hub. Using a 10/100 Mbps switch instead of a hub will prove to be useful as it improves the connection speed. The serial ports of the router can be configured to connect to the MAN Service Provider. NAT can be configured on the router. The systems can be connected to the hub/switch. The default gateway of the systems should be configured with the Ethernet address of the router. The systems can be connected to the hub/switch using a 10/100 base-T cable. The Ethernet port of the router can be connected to the hub/switch using a transceiver. You may need additional network management software depending on the size of your network. You can use SNMP-based PC Anywhere software from Symantec for managing your network.

I have an 8-port hub from Compex that currently allows me to connect up to eight systems. If I need to connect to more systems, would I need a 16-port hub or can I do it with an 8-port one. Currently, the eight systems access the Net through ICS (Internet Connection Sharing). If yes then how should I go about connecting it for more systems?

You can add another 8-port hub to your network. But you will be able to connect only 7 systems to each Hub, as you will need one port each from both the Hubs for an up-link between them. So totally you will be able to have only 14 systems in your network. If you need to have 16 systems in your network, you will have to use a 16-port Hub.

I am trying to connect two PCs, one running Windows 95 and the other Windows ME. The PCs recognize their respective network cards but have trouble getting each PC to recognize the other. I keep getting a message 'entire network without local drives'. The Windows ME PC is being used to connect to the Internet via a dialup modem. I want connect to the Web using the Windows 95 PC as well. Kindly give detailed instructions for setting up both the PCs.

You may face this problem if you have not installed the network components properly.

Ensure that the following network components are installed in both the Windows clients:

  • Client for Microsoft Networks
  • File and Printer Sharing for Microsoft Networks
  • Both NetBEUI and IPX/SPX protocols are installed on both computers

To install Client for Microsoft Networks:

  • Click Start - Settings - Control Panel, and then double-click Networks.
  • On the Configuration tab, click Add.
  • Select Client, and then click Add.
  • In the Manufacturers box, select Microsoft. In the Network Clients box, click Client For Microsoft Networks, click OK

To install File and Printer Sharing:

  • Click Start - Settings - Control Panel, and then double-click Networks.
  • Click Add - Service, and then click Add.
  • In the Manufacturers box, select Microsoft. In the Network Services box, click File and printer sharing for Microsoft Networks. Click OK.

To install NetBEUI and IPX/SPX protocols:

  • Click Start - Settings - Control Panel, and then double-click Networks.
  • Click Add - Protocol, and then click Add.
  • In the Manufacturers box, select Microsoft. In the Network Services box, select the respective protocols. Be sure that at least one protocol is installed on both computers.

Restart your computer when you are prompted to do so.

Note: You might be prompted to insert the Windows CD to install certain components.

Sharing Internet Connection
You can use Windows Internet Connection Sharing for accessing the Net on both the PCs.

When you setup Internet Connection Sharing (ICS) on the host computer, two network adapters are required for ICS to function properly.

To determine the adapters installed, double-click Network, in the Control Panel. Look in the Network Properties dialog box for the information that is appropriate to your connection type.

For computers that are using a standard modem connection, the following adapters are used:

TCP/IP (Shared) - Dialup Adapter

TCP/IP (Home) - Network Adapter

Please visit the following links for using the Windows Internet Connection sharing for accessing Internet on both the PCs’.

I have four computers networked peer-to-peer and the network works fine. The problem is that the Internet does not work on more than one host computer. I have separate IP addresses for each computer. The operating system is Windows ME.

Please check whether the following protocols and services are installed in all the systems on your Network:

  • Client for Microsoft Networks
  • File and Printer Sharing for Microsoft Networks
  • Both NetBEUI and TCP/IP protocols installed in all the computers

To install the above protocols and enable Internet Connection Sharing, refer to the previous query.
