Local Area Connection Not Working


R

Richard F

I have a Windows XP SP3 system connected to a local ADSL Modem/Router which
acts as the DHCP server. Other PCs attached to this router (XP and Vista)
are working fine.

The problem system successfully obtains and IP address from the router but
does not communicate on the network. If I disable the connection and enable
it again it obtains an address but still does not communicate. I tried
resetting the TCP/IP stack (netsh int ip reset resetlog.txt) as described in
KB299357. If I do that when I try releasing and renewing the IP address
using ipconfig I get an error message that a file was not found. If I then
idable and enable the connection network operates.

But, once the PC is rebooted I'm back to no network until I go through the
reset, disbale, enable cycle.

Any suggestions?

Hi
Do you have a valid Internet connection with this PC?
If the IP that the computer obtains starts with a 169.xxx.xxx.xxx, then it
is Not a functional IP.

If you run an ipconfig /all before and after the fix the values are the
same:
IP Address: 192.168.0.2
SNM: 255.255.255.0
DG: 192.168.0.1
DNS: 192.168.0.1
DHCP: 192.168.0.1
which (other than the IP address) are the same on the other working systems.
Trying to use IE for internal or external sites or ping the router does not
work while it does from the other systems. Once the "workaround" is done
everything works even though the ipconfig settings remain the same.

Hi Richard,

Thank you for posting.

Firstly, may I know if the issue is that you cannot visit webpages with
Internet Explorer? If you run other network-based applications, such as
MSN, will it work?

At this time, let's try following to check the issue:

1. Boot the computer to "Safe Mode with Networking" and check how it works.

2. Try to upgrade the driver for the NIC. (If you want, please also let me
know the exact brand and model of your NIC, I will help you find the
driver.)

3. Perform a Clean Boot environment to check the issue

How to perform advanced clean-boot troubleshooting in Windows XP
http://support.microsoft.com/kb/316434

4. If it is possible, please bypass the router and estabish the connection
directly to see how it works.

If the issue persists, please also help me gather the following information
for our further research:

1. Collect the MPS Report

1) Download the MPS Report Tool from the following link:

http://www.microsoft.com/downloads/details.aspx?FamilyId=CEBF3C7C-7CA5-408F-
88B7-F9C79B7306C0&displaylang=en

2) After the download is complete, run the executable file. When you are
prompted "Include the MSINFO32 report?", please input Y to continue. After
a while, a CAB file will be generated.

3) Open My Computer, browse to the
"%systemroot%\MPSReports\Setup\Reports\Cab" folder. You can find the CAB
file above.

2. Capture the network packet

1) Download NetMon3.3 from the following website and install it on the
computer

http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=983b
941d-06cb-4658-b7f6-3088333d062f

2) Logon with you Administrator account and launch NetMon3.3.
3) In the Microsoft Network Monitor 3.3 window, click Create a new capture
tab...
4) In the new tab, select all the Network Adapters in the Select Networks
window.
5) After that, press F10 to start NetMon.
6) Try to re-produce the problem.
7) Go back to the NetMon window and press F11 to stop the NetMon.

Please use Windows Live SkyDrive (http://www.skydrive.live.com/) to upload
the files and share their URLs with us.

Hope this helps. If you have any questions or concerns, please don't
hesitate to let me know.

I serviced a computer recently with very similar symptoms. The problem
turned out to be a failing NIC. You might try a substitute even if just to
eliminate the possibility.

I hope it's not a failing NIC - this is a laptop, but I'll keep it in mind.

Thanks.

you and keep me updated.

Just to complete the picture the issue is with all networking (printing,
pings, file access), not just Internet Explorer. I have found that the
problem seems to be intermittent. It seems that occasionally after a reboot
the networking fails which suggests that the issue is a hardware problem. I
have changed the router DHCP and updated the driver and haven't had a
problem since. If I get further issues I'll repost.
