No LAN in network connections?

January 7, 2007 at 14:33:01
Specs: WinXP Pro, Athlon 3500 / 1GB Mushkin
I recently did a windows repair on my step-brother's computer, and I had to reinstall all the drivers and whatnot. I installed the network adapter (built into the motherboard), yet the Local Area Connection shows up when I view connections.

Any help on what could be causing this not to show up would be great.

The repair process probably didn't do the trick. Have you tried resetting the TCP/IP stack, applying winsock and/or crypto fixes?

The TCP/IP stack (netshell) can reset manually by simply going back and using the classic command prompt screen.

Hit the Windows Logo Key, if your keyboard has it, and then alternately press the R key.

OR

Simply go to Start -> Run

THEN

Type in the given text field: cmd

Press Enter key or click OK/Run.

A black screen with a blinking cursor and some nifty white text should appear (should bring back some memories!). Go ahead and type in the following, EXACT:

netsh int ip reset resetlog.txt

Go ahead and press the Enter key when your finished typing this out.

It should just execute, and when complete, go ahead and exit out of the command prompt window. Finally, go ahead and if you haven't already, run the winsock fix (it supposedly does the netsh fix in this tool, but we did it just in case!), which can be downloaded on line through a simple google search. Then reboot your machine. See if this does it, if not, try the crypto fix. It usually works to machines that have a hard time updating through MS windows update website, but i've seen this fix work miracles for networking issues.

If all else fails I would try three things...

1) Re-install the LATEST driver for your network card. If nothing happens STILL, pop another one in a PCI expansion slot, and see if this is detected and installed properly by windows XP. It's preferable you use a standard PCI 10/100 Intel PRO LAN card or something by Linksys, since Windows should have stable generic drivers for most of these cards. If you can see the expansion card in network connections as a Local Area Connection, I would say that your integrated LAN MIGHT be defective, but I doubt this.

2) Do a complete OS restore. This means basically to back up all your data that you absolutely need, and perform a full Windows XP installation from scratch. Boot to the CD, make sure you format your hard drive, use the full format if you want to write zeroes to the drive, guaranteeing that all your previous data will be gone, and then reinstall XP through the Windows XP setup screen. Sometimes these windows repair sessions don't do the trick... they copy over usually just the essentials, like DLLs, popular EXE files, etc.

3) Apply or Reinstall Windows XP Service Pack 2. This usually fixes errors such as corrupted Windows Firewall/Security Center, and it may fix your network connections service. IDK which service it is in Windows XP, i think its the Network Connections service? Go ahead and check to see if its running, or if its even there (think administrative tools in control panel).

Still want more help? PM me or just re-post with your progress, and good luck!!

I'm assuming you meant LAN Connection does NOT show up w/ "yet the Local Area Connection shows up when I view connections".

I'd test the NIC (With Diagnostics per the MB/PC/NIC Mfgr) first before doing all that....they do go bad.

Just another stupid saying...

Yes, that's what I meant. Sorry for the confusion. I will certainly test these suggestions when I get the chance (sometime tonight) and post back.

Thanks!
