I have Vista basic edition. At the CMD command line, I cannot
ping anything successfully (e.g., www.cnn.com, www.google.com).
However, with my broswer, my Internet connection is working fine.

Any idea why that might be? Thanks, Alan
 
norton, mcafee, any third party firewall
also spyware/malware/virus can cause problems

Are there any likely suspects (settings)? Thanks, Alan

Just because a domain has an HTTP (WWW) server doesn't mean it has to
respond to pings. And these two domains apparently have chosen not to.
 
Google responds to my ping, CNN does not.

Hmm..neither responds to my ping. Microsoft.com doesn't either, for
that matter. Could be my employer's firewall, I suppose.

Tim: Our firewall blocks outgoing ping requests, also, except I have been
set up as an exception in the rules, so I can keep tabs on the internet (I'm
one of the IT guys.)

I went to whatsmyip.com and ran the ping test, which failed. I
also looked around on the Internet for similar problems and
solutions.

In the Network and Sharing Center, I have the following turned on:

Network discovery
File sharing
Public folder sharing
Printer sharing

Password protected sharing and Media sharing are off, and the
network (home) is designated as Private.

Windows Firewall is off. I turned I disabled all non-Microsft
services and everything automatically started (including anti-virus)
using MSCONFIG and rebooted. Same thing --- ping still fails. I can
ping myself but nothing else.

Not sure what else to try! Thanks, Alan

Hey All,

One thing I thought was important was that the XP pinging protocols vs
Vista protocols have changed. On the XP systems you have a ICMP
(Internet Control Message Protocol) ping protocols, but they have now
been disabled on the Vista due to updated security by Vista.

I am working on a work around, and I believe that the only one
currently out there is to disable your UAC and try to ping again.

Will update when more information is available to me.

I have no problem ping anything with UAC enabled where the FW on the other
end is not actively refusing ping requests. What does UAC have to do with
the usage of ICMP?
