Actually, one of the "nice" things about Yahoo.com is that it DOES respond to pings. Most other major sites don't. I just tested it and it's responding to Ping.

OP:
What happens if you type: "Ping 69.147.114.224" ? That's one of Yahoo's servers that is currently responding to Ping.

Also, what is the response if you type: "NSLookup Yahoo.com" ?

ping:
'request timd out'

nslookup:
server: dslrouter
address: 192.168.1.1

non-authoritative answer:
name: yahoo.com
address: 69.147.114.224, 209.131.36.159, 209.191.93.53

what are those ip addr? a tracert?

Those are the IP addresses of Yahoo.com servers. The servers are identical, but located at different addresses.

What happens if you ping the other two servers:

209.131.36.159
209.191.93.53

All three of those servers answer MY ping requests.

What about "Ping Motorola.com"? That one responds to me, too, on both IP addresses.

Do you have any "Internet Security" packages installed? Like Norton Internet Security, or McAfee's similar product? Those contain firewalls that can be problematic at times.

everything times out

i only have avira antivirus. no firewalls besides the standard winxp one
 
If you have other computers on your network, can you Ping them (by either their name or by their IP addresses)?

"Ping mylaptop"
"ping 192.168.0.5"

What about pinging your own computer?

"Ping localhost"?
"Ping 127.0.0.1"?

same thing w/laptop connected to dsl router.

pinging localhost worked
 
Go to Control Panel and then Windows Firewall. Go to the Advanced tab and then under ICMP, click on <Settings>. Are there any checked boxes?

nothing checked.
what is suppose to be checked? and how did it get unchecked? (i know i didnt do it)
 
The only one checked on mine is "allow incoming echo request" (it's the top one). That sounds opposite of your problem but you never know...

I know that ICMP has something to do with pinging though.
 
The "Allow incoming echo requests" checkbox in XP Pro should be checked (though isn't a prerequisite). If you're pinging, disable your Windows firewall too, btw. Of course, the first thing you should do is open up a command prompt (type cmd from Start -> Run), and type in "ipconfig /all" and "tracert". Those'll help you troubleshoot.
 
XP's firewall doesn't block OUTGOING pings no matter what. So that's not it. This still sounds like a firewall problem, though. Are you sure no other firewall is loaded? It'd have to be in the PC itself, since you can self-ping, but can't even ping machines on your local network.

The fact that you can browse the Internet points AWAY from complete network failure or DNS or TCP/IP issues.

I'm probably missing something, but I don't know what it is. Sorry.

Well, a ping to your laptop doesn't mean much unless you are sure the laptop is set up to respond to pings. Its firewalls need to be open for ICMP (pings). Your internal NIC on your router will probably reply to pings. Try that from your laptop, and if it works, then just try pinging your router from your mis-behaving PC.
 
It may also be that your ISP or someone else down the line is blocking PING requests, try a tracert to Yahoo and see how far it gets.

I don't remember. Have we established whether Pings from that other laptop are getting through to Yahoo? I don't think we established that answer.

If you can ping Yahoo (or elsewhere) from the laptop, but not from the "troubled" PC, then the problem is on the problem PC.

It COULD be the TCP/IP stack. But I'm not clear how you could still browse the Internet with a TCP/IP problem. And pings to LocalHost are working. But heck, I don't have any other answers right now.
