RE: Lost Internet Connectivity


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.

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.

Environment: Windows XP (Home), SP2, HP a320n, 2.08 GHz AMD. Windows
Firewall (off), McAfee Personal Firewall, VS, two-PC network, Motorola modem,
LinkSys router, Comcast Cable. PCI 10/100 Ethernet Connection.

Incident: McAfee detected malware, option: remove, result: Firewall
disabled, Internet connectivity lost. Error: Network Cable Unplugged.

1. Initial Fix: Reboot, re-establish network, trouble shoot modem,
connection, etc. Swapped cables, end-to-end, replace cable. Result: No
Change. Connection to second PC Maintained. Direct connect to modem, retry.
Result: No Change

2. Un-installed McAfee with McAfee utility. Reboot, etc. Result: No Change

3. Hardware Fix: Disabled PCI 10/100, installed D-Link 10/100 Fast Ethernet
Card. Installation recognized, Connection listed, re-installed network.
Result: No Change. Un-installed NIC (PCI 10/100), reinstalled. Result: No
Change

4. Trouble-shooting finds: Windows Firewall/ICS Service not running, cannot
start. ipconfig tool not available due “Internal error, request not
supported – Unable to query Host Name.” DHCP Client – not running, cannot
start, error 1068. Attempted manual start of Windows Firewall/ICS Service
returns Error 2 – System cannot find file specified. PING returns null result

5. Run services.msc cannot manually start Firewall. Attempted fix with
NETSH FIREWALL RESET after loading rundll32 setupapi,InstallHinfSection
Ndi-Steelhead 132 %windir%\inf\netrass.inf NETSH FIREWALL RESET returns “OK”
but Firewall/ICS start continues to return “error 2: Windows cannot find the
file specified.”

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:

SERVICE_NAME: sharedaccess
TYPE : 20 WIN32_SHARE_PROCESS
START_TYPE : 2 AUTO_START
ERROR_CONTROL : 1 NORMAL
BINARY_PATH_NAME : C:\WINDOWS\System32\svchost.exe -k netsvcs
LOAD_ORDER_GROUP :
TAG : 0
DISPLAY_NAME : Windows Firewall/Internet Connection Sharing
(ICS)
DEPENDENCIES : Netman
: WinMgmt
SERVICE_START_NAME : LocalSystem

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
Settings\Owner> What file? Where to obtain? Comments/Suggestions
appreciated. Thanks.
