I'm having a bit of a Windows XP SP3 networking issue. Basically I have lost my "Local Network Connection" and nothing I do brings it back. I've tried Add/Remove Hardware, I've uninstalled and reinstalled all network related drivers (or all I was aware of) and nothing works.

It all started with a Virtualbox network bridging issue. So I deleted all network connections with the hope of being able to set them all back up. Things actually found themselves on the first go-round, but I started having the same issues at which point I uninstalled and reinstalled Virtualbox. It was at that point that all my "Local Network Connection" went away for good, never to be seen again.

For now, I can plug in a USB wireless adapter and I have network access, but this is a pain as I'd prefer to be hardwired. For the record, there is nothing wrong with the actual Ethernet port. The system is an Ubuntu/Windows dual-boot setup, and all works fine in Linux.

Any ideas short of wiping the Windows install?

Thanks.

Is the NIC hardware disabled in Device Manager? –  xeon Sep 2 '09 at 23:51

I'm not pretty sure if my procedure would help in anyways but I'd give it a try...

  1. Load Services.msc, and make sure following services are running:

a) Remote Procedure Call (RPC). Use by client for MS networks.

b) Server

c) Workstation. Both used for MS networks and File/print sharing

d) TCP/IP Netbios helper.

e) Computer Browser. Allow to see other computers on network.

f) Network connections

g) DHCP Client

You can also reset TCP/IP by this command:

netsh winsock reset catalog.

Let me know if it works, if not, I'll search more for you!

Regards, David.

P.S. Is your NIC still in the device manager?

I guess if he's got wireless working most of that can be eliminated since they would completely break networking. –  Col Sep 3 '09 at 7:52

Two thing to check, is the lan card enabled in the BIOS and is it visible in device manager. If it is visible in device manager then delete it and do a scan for new hardware to allow it to redetect itself.

My suggestion would be to reinstall the network adapter, as this creates a new connection and rebuilds its networking stack:

  1. Go to Start -> Run and type in devmgmt.msc and click OK.
  2. Find your network adapter that is not showing up correctly in your Network Connections folder, right click it, and select Uninstall.
  3. After the device disappears from the device list, right-click some of the white space and choose Scan for New Hardware.
  4. The device should be found and reinstalled, and it should build a connection for it in Network Connections, and it will probably have a new number with it, which you can rename if you are picky.

If your wireless connection shows up in your Network Connections folder, at least the folder itself is working (I've seen it completely corrupt before and that required a Windows reinstall >.>).
