Result: No Change. Un-installed NIC (PCI 10/100), reinstalled. Result: No

6. Device Manager indicates that the PCI 10/100 is working properly and that
there are no conflicts.

7. WMI is started (automatic) Cmd /k sc qc sharedaccess returns:

It would appear that the crux of the problem is No. 4 above in that some
file that is required for the service to run is missing from C:\Documents and

appreciated. Thanks.

There are a number of TOOLS you can download which will repair a corrupted
TCP stack and Winsock. Try one of these. I like XPWINSOCKFIX.EXE which can
be downloaded at Snapfiles: http://www.snapfiles.com/get/winsockxpfix.html

This will often fix these kinds of problems.

Hi Tom,
I think you have bad Hardware, either the Modem which is my guess given up
the ghost and you can confirm that by taking a machine to another connection
and test to see the machine NIC is okay.
If it did connect after adjusting the settings ( you may or may not need to
adjust the settings) that mean the Modem or one of your hardware
(Modem/Router/Line cable is bad).
Sometimes the ISP test confirm the Line good or bad according to when it end
into the first Phone Plug on the wall and the reset is your priority to
confirm is good or bad.
How long this was going On, if it for a couple of days try system restore to
a week before this happened.
HTH.

The modem is obviously working correctly - or I wouldn't be able to connect
to the 'Net and participate in this forum. All throughout this week-long
nightmare, the second network PC has continued to function with its Internet
connection. As stated previously, cables have been both swapped and
replaced, so I believe the issue is not hardware related, especially as I
replaced the PCI 10/100 with a fast ethernet card.

I ran the winsock repair utility (this is the third such utility) without
any change. The persistent problem has been the inability to start the Win
Firewall/ICS service and the inability of Windows to recognize the PCI
ethernet connection, along with the ipconfig, ping, etc returning null
results.

Bob,

If your problem is related to LSP / Winsock corruption, as previously stated,
there are multiple repair tools, none of which is more effective than any other.
Depending upon what your problem is, you are advised to run each one, one at a
time. If any one makes a change, you should run each one again. And reset
TCP/IP too (IP and Winsock are not the same component).

If the problem originates from the Windows Firewall service, which does fail
open (ie if its stopped, no traffic is passed), you may have to check Event
Viewer for clues. And ensure that Remote Procedure Call service is running.
