Network LAN and 3G connections on Thinkpad X61 Windows XP deactivated

Hi

My Thinkpad is now not able to connect to LAN and its 3G not connecting too.

In the past 2 months when this happened, I would do a "system restore", a feature
found under "System Tools" but about ten days ago, this did not help.

Did not install anything new or remove anything from the Thinkpad, only saving
data.  My Anti virus is quite up-to-date

Attached the system logs from Event Viewer in text format  which showed quite
a lot of network error

When this X61 first boots up, it's CPU is at 100% due to 3 processes mostly :
tvt_reg_monitor
TSC
DKservice

Sometimes, I used Taskmgr==>Processes  to kill the above 3
upon bootup to speed up the booting up

Let me know if you need further information to troubleshoot this

Thats an old log......

Stop those services from running. Or uninstall the associated apps if not needed.....

No one single set will work for everyone. This site above is probably the best online in regards to trimming out services. Will help with your boot time.....

Does Safe Mode w/ Networking work?

Are teh following services started, and set to automatic in Start>run>services.msc.....

Network Connections
DHCP
DNS
Netbios TCP Helper

Make sure that you can ping by name and/or IP address.....

Start>run>cmd.exe

ping 4.2.2.2
ping google.com

Do both of these fail, or just one?

To totally rebuild your network connections.....

Go to the Device Manager>Network Adapters, and remove ALL NIC's from the device manager..

In the Device Manager, select View>Show Hidden Devices

(If the Show Hidden devices is not present, do the following command from a command prompt..)

start>run>cmd
set devmgr_show_nonpresent_devices=1

More information on that command here....
Device Manager does not display devices that are not connected to the Windows XP-based computer
http://support.microsoft.com/kb/315539

Go back to Network Adapters in the Device Manager, and make sure your adapters are all gone, including any older ones. (there will be several ' miniport' devices that are not able to be uninstalled....)

Then....

Start>run>CMD.exe

netsh int ip reset reset.log
netsh firewall reset
netsh winsock reset

Reboot and let Windows reinstall them...

Then make sure that the SP2/3rd party firewalls are all disabled, and retest....

For extreme cases, where TCPIP is totally shot.......

How to remove and reinstall TCP/IP on a Windows Server 2003 domain ...
http://support.microsoft.com/kb/325356

This article allws you to UNINSTALL (yes, uninstall, by removing the limitation that greys out the uninstall button) and reinstall TCPIP (not just resetting the stack). I have tested this, and it does work. For XP though, please start with line 5.

Network Connections
DHCP

All the above are "Started" and all are "Automatic" except "Network Connections"
which is "Manual" but strange that it's "Started" upon bootup : something must have
started it?


In Safe mode with "Networking" on, LAN NIC port works but the 3G can't detect the
device and after installing the necessary drivers/software that comes with the 3G
broadband modem, it requires a reboot.

I'll take an Acronis backup first before reinstalling entire Networking
