RE: Lost Internet Connectivity

nass -

Thanks for the suggestion(s). I had forgotten that I had previously
"successfully" reset the winsock catalog. Having done it (once again) the
result is the same: Network Cable Unplugged. One aspect is the inability to
use network diagnostic tools, i.e. ipconfig, ping, etc.

I have un-installed and re-installed the 10/100 PCI Ethernet device several
times, with the same result. I cannot raise the router at 192.168.0.1, nor
does it help switching from auto to manual (and back again). It still
appears to me that the problem lies with the Win Firewall/ICS service not
started, and unable to be started manually.

I have isolated the PC and tried a direct connection from the modem to the
PCI, with the same result. While the trouble-shooting sequence indicates
that the PCI is present and functioning correctly, it doesn't seem as if
windows recognizes that there is a PCI Ethernet adapter installed at all!
For example, I went back and tried to "start over" with the install CD for
Comcast and received an immediate error to the effect that no Ethernet
hardware was recognized with the admonition that I shouild install same. It
seems that I'm caught in a loop.

Can you point me in another direction?

Incident: McAfee detected malware, option: remove, result: Firewall

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.

I think your machine (s) are infected, since removing the Malware which my
guess is more than this.
You need to isolate these machines, disconnect all machines turn the Router
OFF wait for a minute or so, plug the Router to the Power then Turn the
computer (one computer for testing leave the rest disconnected)., does the
Connection establish itself, also are you able to access the Router web page
from this machine by entering the IP address for the router: 192.168.0.1?.
Do you implement an encryption method to secure this network, also do you
select the right network (SSID) which you created when you set up the Network
connection?.
- Are you using Static or Auto IP address, check your TCP/IP settings for
IP, DNS.

Open a run command and type in:
ipconfig /flushdns click [OK]
ipconfig /renew click [OK]
netsh winsock reset click [OK]
Reboot your machine, do you have connection and stable one?.
