My Windows XP computer just spontaneously removed itself from the network – or did something similar. It was working fine, I was on the internet etc, and I left my room for a minute, came back and AIM had disconnected, MSN had disconnected, and I was getting 404 errors everywhere I tried to go. All of the other computers on the network, including this one (sitting right next to it) are still on the network/internet and work fine.
Anyone have any idea what could have caused this or how I could potentially fix it? I tried a reboot – but it didn’t work.

Start-\>Run-\>“cmd” w/o quotes-\>Dos window comes up-\>“ipconfig /release” w/o quotes-\>Enter-\>Wait until the command line comes up again-\>“ipconfig /renew” w/o quotes. Try that.

I tried that last night before I went to bed – twice. The first time it said it couldn’t find the DHCP host and the second time it worked, but the network still didn’t. This morning when I woke up my computer worked on the network, I got home and during the day everything had disconnected again, but was already back (could tell because my mail script had a server error and messengers had disconnected).

Is there an IP conflict between that PC and any of your other computers?

I don’t know, how would I check?

Pull out the ends of your Cat5 cable and clean the male and female components on both ends.

Done, hopefully that will do the trick. =)

There are 5-6 computer connected at a time
Here’s the setup:
Modem
—|---
Router
|||-|-|
123| 6
—||-
Switch
–||–
–45–
1 - OSX/OS9 Bubble Mac
2 - HP Pavililion
3 - HP Laptop
4- My Dell, the one that’s having problems
5 - Linux Server
6 - Old Laptop connected wirelessly occassionally
I’m only rarely having the problem now though, it’s only happened once in the last 24 hours or so, I think the cleaning helped a bit.

Maybe its a problem with your server and your Dell hogging the switch?
