Can you "ping" the Internet, say www.Yahoo.com?
(Open a command prompt and leave it open...)
Ping www.yahoo.akadns.net
Ping 216.109.117.204
The second is the same place but skips the DNS resolution.
If the first fails and the second works you machine isn't properly
configured with a DNS server address (in NIC properties)
In that case output following to a text file and report it here:
ipconfig /all > ip.txt
IF the second one fails, try the following and report the result:
tracert 216.109.117.204
If you have some kind of firewall you can test DNS buy using
both http://www.yahoo.akadns.net and http://216.109.117.204
in Internet Explorer (again the latter skips DNS.)
[Firewalls commonly block the protocol used by TraceRt and Ping.]

Comcast has been to my house twice. each time they insert
a floppy disc & remove something. it works to connect
maybe twice then i get the same dns error. I asked comcast
if I can copy disc he said no it's their own special
program & he's not sure what it is. I'm completely at a
loss. Anyone help please!!

I would disagree - ping failed.
So we know we have something WORSE than (or in additon to)
a DNS problem. Either routing is failing or ICMP is blocked, but
since you took down the firewall the likely culprit is routing.
Consider though that the ping (ICMP) might be block later in
the route (e.g., at the ISP) -- this is the reason that when ping
fails we switch to Tracert to determine HOW FAR and through
WHICH ROUTERS the traffic is suffessful.
Tracing route to 216.109.117.204 over a maximum of 30 hops
1 * * * Request timed out.
2 * * * Request timed out.
So you have an IMMEDIATE routing failure -- every machine
"routes" for itself even if it isn't a router. This implies that either
the machine is misconfigure or the FIRST router is failing.C:\ping www.yahoo.akadns.net

The above should not happen, at least no for a variety of sites.
You failed to ping 216.109.117.204 by address and succeeded
with a DIFFERENT site by name -- you really should consistently
test the SAME IP (by name and address.)
Remember: ALL IP traffic ALWAYS travels by IP -- DNS names
are just a courtesy for humans that must first be resolved BEFORE
the actual message is sent.

Go back and test with teh SAME IPs (as your successes)
using mainly Ping and Tracert.
You are going to have to learn IP troubleshooting but it sounds
like Comcast has routing or config problems.
You saved the IPConfig but didn't send it.

Herb, I've seen these issues with Comcast. Provided it's not a personal
firewall causing it, which doesn't seem the case here (or maybe) but need to
disable it to make certain to eliminate that possibilty. I used to deal with
Suburban Cable, the provider in the Philly region before Comcast bought them
out, it was fine, but once Comcast came into play, all kinds of issues came
about. Considering that Rosie has possibly had this as on going problem,
then I would suspect Comcast's routing is not configured correctly, as is
the consensus among my peers in this area, that this happens often. It takes
about 4 - 5 hops just to get out of their network, including NAT'd subnets.
So I wouldn't doubt this is on Comcast's side. Another issue is that there
can be an issue with the actual line coming into the house. Since they have
multiple 2-way amps and nodes before they even hit the pole. I had to have
Comcast come in 3 times since Dec (when I got rid of my T1 and got their
service), complaining about intermittent connectivity, each time saying that
it;s not their fault, until one day, it was so bad, I called them and said,
listen get someone out here right now, it;s happening again and if you
don't, I'm dropping the service, including their TV service, since some
channels that day just wouldn't come in. They had a crew out there in an
hour. They determined it was a line issue, and had to get an infrastructure
maintenance crew to take care of the line and the amps coming in, replacing
whatever and finally they straightened it out.
If this is an ongoing problem, and it's not Rosie's config, then if I were
her, I would complain until I get some sort of resolve. There's always
Verizon DSL. Slower, but no hiccups whatsoever, as per a couple of my
neighbors.

In no sense was saying he might not need to temporarily

I was referring to people who block themselves with a tight

Herb I just want to thank you from the bottom of my
rosie said:internet services because I was down so much. They were
out to my home last week & installed a new line
underground. I was able to get online right away but only
for 1 day then I have to disable firewall to get on. I
will call comcast again. They were out twice before
installing the new line & inserted a floppy disc & removed
something. I asked what or if I could copy the disc they
told me no it was cables own program.
