Cannot Ping Beyond Default Gateway & DHCP Server

My neighbor finally took the plunge to upgrade from dial-up to cable, but
cannot access the internet through it. He’s using XP Home, directly
connected to cable modem – service by Time Warner, which works fine for me
next door. His dial-up continues to work fine, but access through his
Ethernet local area connection does not. TW confirmed (with their own
laptop) that the connection & modem are good, so problem must be in his
computer.

Network Diagnostics shows pings to his IP, Default Gateway, and DHCP Server
work, but pings to DNS servers fail. Verified manually (pings to those DNS
from my computer work, so it’s not the DNS themselves). Pings to other IPs
(e.g., Google’s) also fail. Connection’s Status shows lots of packets sent,
but almost none received. Uninstalled Norton 360 with no effect. No other
security software present, Windows Firewall turned off. TCP/IP properties
and IP addresses received (DNS, DHCP) look fine (same external IP addresses
my computer gets).

Other things checked:
Boot in Safe Mode yields same results.
Device Manger shows no problems with Network Adapter or (hidden) TCP/IP
drivers.
Packet Filtering is off.
All Windows components (needed or not) are installed, all services
(needed or not) are started or on auto.
Windows SFC ran OK.

From all the sage advice I found on this board, here’s what I’ve tried
(without success):
reset TCP/IP (netsh int ip reset)
turned off ipsec service (temp)
ipconfig /flushdns
ipconfig /registerdns

So: dial-up works fine, and Ethernet HW/SW gets as far as gateway & DHCP,
but can’t get to DNS nor anything else.

I’m a bit over my head, and sure need some advice. Thanks.

Posting the result of ipconfig /all may help.

Hi Bob

Results from our problem computer. through ethernet connection:

For comparisons, I (1) did the same tractrt on my own computer (next door,

ethernet was disabled and its dialup was enabled.

These results seem consistent with previous symptoms, aren't they? If they
tell us something more, it's over my head (and I'd appreciate education if
there's something here I don't see).

It seems to me that something inside this problem computer is allowing
replies coming in through dial-up to pass through OK, while it is blocking
most (but not all) replies coming in through the NIC. (Replies to messages
addressed to default gateway and DHCP server get through OK, so I'm guessing
the NIC and its driver cannot be the guilty party). What little setting or
table in Windows XP/SP3 Home could cause this symptom?

Thank you for your help.

In case anyone is following this, here are today's developments:

Took my neighbor's problem computer to my house and connected it directly to
my Roadrunner modem. His computer accessed the internet OK without problems.

Took my healthy computer to my neighbor's house and connected it directly to
his Roadrunner modem. Got the same problem symptoms (can connect, receive IP
address from DHCP, and receive addresses of DNS servers, but cannot ping nor
access the DNSs nor anything beyond the Default Gateway).

Spent a few hours on phone with Time Warner (Roadrunner) level 1, 2, and 3
support trying lots of things, even swapping out the (new) cable modem
(desperate). Nothing worked.

We are about to give up, with my neighbor resigned to spending the rest of
his life on dial-up.

Any ideas?

cannot access the internet through it. He’s using XP Home, directly
connected to cable modem – service by Time Warner, which works fine for me
next door. His dial-up continues to work fine, but access through his
Ethernet local area connection does not. TW confirmed (with their own
laptop) that the connection & modem are good, so problem must be in his
computer.

Network Diagnostics shows pings to his IP, Default Gateway, and DHCP Server
work, but pings to DNS servers fail. Verified manually (pings to those DNS
from my computer work, so it’s not the DNS themselves). Pings to other IPs
(e.g., Google’s) also fail. Connection’s Status shows lots of packets sent,
but almost none received. Uninstalled Norton 360 with no effect. No other
security software present, Windows Firewall turned off. TCP/IP properties
and IP addresses received (DNS, DHCP) look fine (same external IP addresses
my computer gets).

Other things checked:
Boot in Safe Mode yields same results.
Device Manger shows no problems with Network Adapter or (hidden) TCP/IP
drivers.
Packet Filtering is off.
All Windows components (needed or not) are installed, all services
(needed or not) are started or on auto.
Windows SFC ran OK.

From all the sage advice I found on this board, here’s what I’ve tried
(without success):
reset TCP/IP (netsh int ip reset)
turned off ipsec service (temp)
ipconfig /flushdns
ipconfig /registerdns

So: dial-up works fine, and Ethernet HW/SW gets as far as gateway & DHCP,
but can’t get to DNS nor anything else.

I’m a bit over my head, and sure need some advice. Thanks.

In case anyone is following this, here are today's developments:

Took my neighbor's problem computer to my house and connected it
directly to
my Roadrunner modem. His computer accessed the internet OK without
problems.

Took my healthy computer to my neighbor's house and connected it
directly to
his Roadrunner modem. Got the same problem symptoms (can connect,
receive IP
address from DHCP, and receive addresses of DNS servers, but cannot
ping nor
access the DNSs nor anything beyond the Default Gateway).

Spent a few hours on phone with Time Warner (Roadrunner) level 1, 2,
and 3
support trying lots of things, even swapping out the (new) cable modem
(desperate). Nothing worked.

We are about to give up, with my neighbor resigned to spending the
rest of
his life on dial-up.

Any ideas?

He could move in with you, simple!

Thanks (really). I needed that moment of lightness.
