Can not connect to internet after ME to XP upgrade

[Guest]

Hello,

I upgraded (not fresh install) my home desktop from WinME to WinXP and
since then I am unable to connect to internet. I am connecting via LAN using
cable modem. It has been working fine before upgrade but am unable to connect
since upgrade. Here is my desktop info:

Compaq Presario S5005
Pentinum III 933 MHz
256 RAM
60 Gb Hard drive
Network card is "SMC EZ 10/100 SMC1211TX".

I have checked everything. Network connection is enabled and XP says
working. I am able to get IP address (tried ipconfig). It shows me a valid
IP address assiged by my Belkin wireless router (192.168.2.72). I am unable
to do "ipconfig /renew", it syas unable to renew IP address. I am unable to
connect to net via IE. I have checked all IE settings and everything looks
fine.

I have even tried to disable the LAN connection and re-enabled but still
same problem.

I ran the Network Setup Wizard but the last page showed following:

Cannot Complete the Network Setup Wiard
An error occurred during configuration of the network on this computer.
You can configure your network manually, or you can run the wizard again
with different settings.
To close this wizard, click Finish.

On the "Select a connection method" screen I selected the first option i.e.
"This computer connects directly to the internet. The other computers on my
network connect to the Internet through this computer."

In nsw.log file, except for few other informative statements (as to enabling
this and starting that), the only one close to error message looks like this:
"Adapter configuration for home networking failed."

Can somebody pl. help me figure what is wrong? How to diagnose
and fix the problem? Any comments, suggestions or pointers will be much
appreciated.

PS: I have two other computers connected to the same router and everything
is working fine on those. The problem is only on this one that I upgraded
from ME to XP. I had tried to connect this computer directly to cable modem
but same problem. When I do this, though the IP address is now assigned by
comcast but still can not access net.

Regards
Shail

Do a simple test. can you ping the router. If yes, can you ping a public IP? if yes, can you ping yahoo.com?

Try:

1. Open IE, click Tools/Internet Options/Connections tab.

2. Select Never dial a connection.

3. Click LAN settings button and clear all check boxes.

4. If the above does not work, open a command prompt and:

ping 4.2.2.1 ENTER.

5. If #4 works, try:

ping yahoo.com ENTER

If #4 works and #5 does not, or neither works; try manually setting your IP
address, subnet mask, default gateway and primary DNS server. Use the IP of
your ISP's DNS server for primary DNS:

Doug,

I tried all this and nothing worked. I still have the same problem.

1. Configured IE as per step 1, 2 & 3 below.

2. Ping 4.2.2.1 fails

3. Ping yahoo.com and yahoo.com 80 fails

I initially had this computer connected behind a Belkin wireless router but
now I have it directly connected to my cable modem.

4. Having DHCP as source for IP address, I tried to ping my own IP address
(that ipconfig shows for me) and even this does not work.

5. I don't have static IP address from my ISP but I still configured it
using the IP address I got from them when in DHCP mode but this also didn't
make any difference.

One other thing I want to mention, before I upgraded to XP, I had a software
firewall (Zonelab Integrity) installed on ME. While doing the upgrade it was
mentioned that this firewall needs to be reinstalled and I continued with it.
Now after upgrade, though I don't see this firewall running but when I go to
Control Panel -> Add/Remove Programs this firewall is listed there as one of
the installed product. I had tried to de-install it but it ask me some
password. I have no idea what that password could be. I have tried all
possible passwords that I could have used but it just does not like any one
of those.

Do you think this firewall could be causing problem? Would you know how can
I get rid of it without knowing the password?

Thanks a lot for your help.

Yes - this problem could be related to the prior ZoneLabs installation -
this kind of software can be notoriously difficult to remove and partial
removal can cause various problems. If possible try reinstalling the
product and then use its native uninstaller to remove it.

Also, try using a direct connection to the modem again - set TCP/IP to
automatic for everything and shut down the computer. Disconnect power to
the modem and wait several minutes. Then repower the modem, connect and
boot the computer.

Thanks Doug, that was it.

ZoneLabs firewall was the culprit. As suggested, I reinstalled it and things
started working just half way in the installation of this software. Once
completed, I was able to connect to internet, ping everything. So things are
back to normal as before upgrade.

For now I have stopped it, disabled it and exit out of it (I have not
de-installed it yet). And still things are working fine.

Do you know is there any advantage of running his firewall given that XP has
its own firewall? Can we run both XP and ZhoneLabs firewall together, is it
advisable?

Thanks for all your help.

The XP SP2 firewall is pretty good. Probably, the ZoneLabs firewall has
more feature's which may or may not be of use to you and it may provide
better protection. You should not run both. If the machine works with
ZoneLabs enabled, I would stick with it.
