Troubleshooting Network Connections
Posted on 2003-03-21
Hi, I'm responsible for helping people out here with computers (although I don't have much real training). I have a problem mainly with the Windows 98 computers. Most work fine, but some seem unable to obtain an IP. Running 'ipconfig' gives an IP of the form 169.xxx.xxx.xxx, which I know means that a proper IP couldn't be obtained. 'ipconfig /release_all' fails to reset these to 0.0.0.0, and similarly 'ipconfig /renew_all' simply takes a long time, then returns with the 169.xxx.xxx.xxx IP.
I've tested these computers with different cables, so I know that is not the problem. It *has* occurred before that the hub or data ports in the individual locations are faulty, but in many cases I've used a known working laptop to test the rooms' connectivity.
I am wondering mainly what would you do to find the source of the problem? It's a hassle to try different network cards so I'd prefer isolating the problem before then. Similarly, reinstalling Windows would probably help but I feel it's more effort than necessary. A friend commented that it may be a corrupt TCP/IP stack, but I don't think that would account for all the cases.
One more bit of information that may help is that in many cases there are multiple devices installed when running 'ipconfig'. These are usually something like infra-red ports or modems etc, but sometimes I have no idea what they are.
So basically: is this a known issue with Windows 98, and how do I go about isolating/fixing the problem. Be as detailed or vague as you like, anything could help! I don't have many points to give, so don't try too hard if you feel it's not worth the effort :)
Thanks for your time.
