LAN lost, but can ping
Need help in getting home LAN that connects to Internet up
and going again. Friend in Cal., lost network after teenager did something to system. Poor lady has 10 children. Which is enough. Not much money, so having someone come out to work on it is financially difficult. She also has inoperable brain cancer, so stress is really bad. She needs her communications back I'm an MCSE (NT) I know a bit but without seeing what's going on it's hard to diagnosis the network issue. -- Trying to help her on the phone, Utah to Cal is difficult. She doesn't understand drivers or how to install them, X cables, straight cables, know what kind of LAN cards she has, PCI, ISA, switches, gateways, routers. She is though pretty smart and willing to try whatever I tell her. From what I understand, here is the setup: Home LAN of two Win98 machines, with modems, connected by cable to a Soho 8 port switch (unknown if it uses crossover or if it is pingable.or addressable), with one computer acting as a gateway, connected by modem to Earthlink, both computers and a printer plugged into the switch by Ethernet & CAT5. All used to work; now she can't reach anything from the 2nd computer. There is no network connectivity through windows to the gateway computer or to the printer. But the when she connects the cables to the ports, the lights on the switch light, showing the switch is seeing the hardware? Connecting each computer directly to Earthlink, through the modem, works. IE/OE both funciton, through direct connect. I had her put things back like they were and do a 127.0.0.1 ping on each machine. Loop back test worked, so I assume LAN cards & drivers are ok? Then I had her ping each computer's IP address and she said she got a response. [Not sure if this is true or not- she was upset.] If it is true, then that indicates to me that it is a Windows networking problem? Next thought is to have her uninstall/reinstall MS Client for Windows, File and Print sharing; TCP/IP, make sure the computers are on either the same workgroup or set for peer-to-peer. (will having her uninstall the MS Client, File & Print Sharing; & TCP/IP mess up the gateway computer's ability to see the printer? Because that she says, is working. If she has to re-install the printer driver again, she doesn't know what I'm talking about or where it is.) More ideas please? Problem 2) I thought if there is a cable problem or crossover problem with the switch, that would show up when she tries to ping other computer. But she says she can. And as I mentioned, the switch's ports light when a system is plugged in. She may be too upset though to know for sure if pinging is getting through, so for second ideas, lets assume that she can't ping the other systems. If that's the case how to proceed? Same as above? I don't even know how to test cable. She does have another LAN card, thinks it fits the slot, although she said it doesn't look same, so don't know if she's trying to fit an ISA card into PCI slot or visa/versa, but she doesn't have the driver for it anyway. However, I would imagine Win98's generic would take care of that. Please concentrate on scenario 1, first. Then need ideas on the 2nd scenario, in case the systems can't ping one another. Uninstall/reinstall the MS net client & tcp/ip? I don't want though for her to loose the connectivity the main computer has to the printer. Which doesn't make sense either. How can that system see the printer but not the other machine? DHCP problem? I have no clue how or from where the 2nd system is getting it's address. Help please? Thanks, Bob |
