One computer does not connect to the internet

[ABCDiamond]

I have added some of my details to two other threads, but have been looking at this some more today, as I am totally at a loss.

I have two computers and a VOIP phone system through my router.

One computer, and the VOIP work OK, but the other computer will not access the internet, although I get local access between computers.

Looking at the thread at http://www.techsupportforum.com/networking-forum/networking-support/294607-have-signal-ip-addy-etc-but-no-internet.html I see that their problem machine has a Realtek RTL8139/810x Family Fast Ethernet NIC.

My problem machine has a Realtek RTL8139 Family PCI Fast Ethernet NIC

Is it a co-incedence ?


My non working machine has this ipconfig report:

I have tried to restore IE advanced settings, but that hasn't helped.

I also tried to restore the system back a few days, but somehow that stuffed right up, and I needed to reactivate MS Windows XP (by phone) as it somehow thought the hardware had changed. I did upgrade the memory 6 months ago. from 512mb to 1286?mb

Just to add, having read other posts:

I tried to ping Yahoo.com
Good machine works OK
Bad machine "could not find yahoo.com"

But both machines ping 68.180.206.184 with no problems, 190 & 194 ms average.

I have removed your posts in other folks threads. Please do not hijack another thread for your issue, keep the discussion to the thread you have started.


TCP/IP stack repair options for use with Windows XP with SP2/SP3.

Start, Run, CMD to open a command prompt:

In the command prompt window that opens, type type the following commands:

Note: Type only the text in bold for the following commands.

Reset TCP/IP stack to installation defaults, type: netsh int ip reset reset.log

Reset WINSOCK entries to installation defaults, type: netsh winsock reset catalog

Reboot the machine.

Thanks for your reply.

I have just done this, and the report I got is:

Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\>netsh int ip reset reset.log
The following helper DLL cannot be loaded: NAPMONTR.DLL.
The following helper DLL cannot be loaded: DOT3CFG.DLL.


C:\>netsh winsock reset
The following helper DLL cannot be loaded: NAPMONTR.DLL.
The following helper DLL cannot be loaded: DOT3CFG.DLL.

Sucessfully reset the Winsock Catalog.
You must restart the machine in order to complete the reset.

After restarting, I still only get a local area connection.

However, going to http://68.180.206.184 I do get to the yahoo error page

At least I now know that I do have the internet connection, but something isn't converting the words I type to the numbers that the internet needs.

I am learning, but not enough yet ;)

I checked on the location of those two files NAPMONTR.DLL and DOT3CFG.DLL and they are both in C:\windows\servicepackfiles\i386 and C:\windows\softwaredistribution\downloads\dd9....etc

I did notice the creation date of the files are 30/08/2008 but the modified date is shown as 14/04/2008.

On the good machine, these two files are only found in one location C:\windows\softwaredistribution\downloads\dd9....etc
with creation date 26/08/2008 and modified date 14/04/2008

I'd try running SFC: SFC Tutorial
