Cannot connect 1 of 3 pcs to our network

Asked Aug 19, 2006, 04:27 PM — 6 Answers
2 of our 3 xp router hard wired lan pcs see each other. 1 cannot even ping its own IP even though it connects to the Internet just fine. I've done the typical troubleshooting. It's the newest and strongest PC of the 3.

Does it have any 3rd party firewall installed on it like Zonealarm or Norton Internet Security? This could be stopping the lan connection working while the internet is fine. Try disabling the firewall on the pc to test.

Please summarise the typical troubleshooting you have already done so we can discount these things.

There's your problem.
Disabling Zone Alarm doesn't stop it acting as a firewall, only stops the active part of the program.
Best idea would be to uninstall ZA, using the inbuilt uninstaller NOT add/remove, and you'll have access again.

Totally uninstalling Zone Alarm didn't help.

So, you can ping the gateway 192.168.1.1 but can't ping your own ip address? What does IPConfig/all give you? Do you have more than one connection in the back of the computer for lan/internet access?

What does ping 127.0.0.1 give you?

Hint - if you type "ipconfig /all >textfile.txt"

This will output the result into a text file (called textfile.txt) that you can post here easily.

It pings 127.0.0.1 OK.

Is there some type of reinstall I should perform with the Lan adapter?

There's just 1 ethernet port.
