Can't Access Internet: Help....

[michael]

Help, I have exosted my ideas about this strange problem.

Background:
I have a dell PC with Windows XP home which I updated using Microsoft
CD to XP PRO (took me 5 hours with microsoft tech support). After that
the problem is that I can not access the Internet.

System configuration
I have this DELL PC connected by ethernet cable to Router. To this
router connect 3 other PC's via ethernet cables. The router is
connected to cable Internet via cable/modem.

- All other PC are able to access the internet except this DELL.
- All PC including the dell PING each other
- All PC including DELL can see and transfer files between them
- DELL gets the correct IP address, it pings all other PC's, still can
not access the internet.

What I have done to try to resolve it:

1. Reinstalled network card on DELL (did not help)
2. Reinstalled Explorer on DELL (did not help)
3. Installed Opera Browser on DELL (thinking maybe something wrong
with Explorer): did not help

Questions
1. What else Can I do ?
2. Is there a way to UNINSTALL TCP/IP protocol and reinstall again ?
(I was not able to find a way for that)

Any other ideas ?

Really appreciate everybody help.

Thank you.
Michael.

Right click My Network Places on the Desktop.
Click Properties.
Right click Local Area Connection.
Click Properties.

Under "This connection uses....."
Click "Client for MS Networks".
Click Properties.
Select "Windows Locator" from the dropdown box.
Click Ok.

Scroll to and select Internet Protocol (TCP/IP).
Click Properties.

Under the General tab make sure "Obtain an IP address automatically" is selected.
Click the Advanced button.

Under the DNS tab:
Selected "Append Primary and Parent DNS suffixes.
Register this connections address in DNS"

Under the WINS tab > NetBIOS:
Selected Default.
Ok out of MNP.

Reboot if required.
Open a command prompt, click Start > Run, type in: cmd and press Enter.
At the prompt type each command below and press Enter after each.
**Note: Command noted by =, Space noted by ^. Do not type the = or ^.

=ping ^ 192.168.1.1 *Routers IP, change as necessary.
If it times out then there is no communication between the router and machine.
If not then the machine communicates with the router.

=ping ^ google.com
If it times out then there is no connection to the net.
If not then net connection is established and all is well.

ping 127.0.0.1
If it fails it may be a TCP/IP stack problem.

Ping each computer from the other using the UNC:
=ping ^ computername
If it fails either way there's an IP or Name resolution problem.

If pinging times out on any address, to see if the machines IP is correct along with
other settings.
= ipconfig ^ /all
If anything isn't correct, at the prompt type and press Enter after each command (98
may be different):

=ipconfig ^ /release
=ipconfig ^ /flushdns
=ipconfig ^ /renew
=ipconfig ^ /registerdns
=exit
If that fails reopen the command prompt, run release and flushdns only and exit.

Shut down the machine.
Pull the power from the router.
Pull the power from the modem.
Wait approx 30 secs.
Apply power to the modem and wait for it to finish synchronizing with the cable.
Apply power to the router and wait for it to finish synchronizing with the modem.
Power up the machine.
The machine should now be assigned a new IP from the router.
Run ipconfig or attempt net connection to test.

Any other ideas ?

Did you check any firewall rule you may have to make sure it's not blocking your
access?

Really appreciate everybody help.

Thank you.

My mother is experiencing a similar problem attempting to get her cable
connection working (they say it's not their problem). The modem appears to
be working just fine, but she cannot load any web pages (IE 6.0).

How much of the aforementioned help is applicable in a single-computer system?

Thank you.
