Hi,
I have a small network on which all the computers function normally
except
one new one can't get to the internet. There's four wired computers
and
one
wireless on a D-Link DI-624. All computers are either XP home or
Pro.
The
one in question is XP home. I can ping the router, I can see other
computers in the workgroup and their files, and I can see the
offending
computer from others on the LAN. I thought somebody suggested a
website
for
this type of issue, but I can't find the thread now. It's really
frustrating because this is a computer for a security camera system
that
I'd
like to access from home as I once could. Thanks for the help!
Pete

Pete,

If the problem with the one computer is simply Internet access,
let's
look
at
"ipconfig /all" for the problem computer, and for 2 of the properly
working
computers.

Ok. I did the ipconfig /all thing and here's what I got on the offending
computer and another computer that functions correctly. See anything
wrong?

Pete,

One of the things that intrigues me, when I try helping here, is
situations like
yours.

Your stated symptoms:
# A LAN of 5 computers, all able to share files, connected to a NAT router
and
using subnet 172.16.0/24.
# Some computers run Windows XP Home, others XP Pro.
# Some computers are connected by Ethernet, others by WiFi.
# Of the 5, 4 have Internet access, one doesn't.

Your documentation:
# Computer SecuritySystem has no Internet access. IPConfig log shows an
Ethernet connection, with a 172.16.0/24 address, and with DHCP and DNS.
# Computer Pete has Internet access. IPConfig log shows 2 IP connections:
## One connection (WiFi) has a 172.16.0/24 address, and has DHCP and DNS.
## One connection is a bridge, with DHCP server. The bridge is on the
APIPA
subnet of 169.254/16.

I don't see a problem with SecuritySystem indicated here. What,
precisely, are
your symptoms of no Internet access? Please diagnose your problem:
# From a command window:
1. Ping www.yahoo.com.
2. Ping 66.94.230.33.
3. Report success / exact text of error messages.
# From your browser:
1. Browse www.yahoo.com.
2. Browse 66.94.230.33.
3. Report success / exact text of error messages.

Hi Chuck,
I pinged first and browsed second. When I browsed the addresses, nothing
really happened. When I start IE, it says at the bottom "Finding site
www.microsoft.com" and never brings up a page. Could there be a problem
with IE? Thanks
Here's what I got with the pings:

Pete,

If the above is normal, and are seeing no error messages, then you have neither
a connectivity or DNS problem. I'm betting you have an MTU problem.

Or maybe LSP / Winsock corruption.
