Help: Lost LAN connectivity to WinXP desktop

[RLymburner]

PROBLEM:
I somehow lost network connection to a WinXP (SP1) computer on the LAN despite everything looking ok.

OVERVIEW:
- Using DHCP to acquire IP (release/renew no results, gets 0.0.0.0 on reboot) - It's not getting an IP address from my router (Linksys BEFSR41)
- The lights on the NIC card and the router are lit, indicating a good connection, I've tried different ports on the router
- No problems reported by Device Manager
- LAN is ok, connected right now on my laptop (through router to cable modem to net)
- Using Client for MS Networks and TCP/IP protocol
- LAN Connection Icon (bottom-right near clock) indicates proper connection

ALREADY TRIED THE FOLLOWING (none worked):
- ipconfig release & renew (error: "the operation failed as no adapter is in the state permissible for this operation")
- unplug NIC, reboot, plug NIC back in
- Deleting old machine entry from web-based router tools
- change to bogus workgroup name, reboot, change back to proper workgroup
- give static ip and reboot
- changed network cable

Suggestions?

Strange problem.

It sounds like the NIC has failed, but then its strange you get no error in Device Manager.

Even if it cannot get an IP from the router it should get one from AIPA.

Try
Ping 127.0.0.1
Ping localhost.
Timeouts mean bad driver, or bad NIC or TCP/IP stack corrupt.

There are some other tips here:

There is a useful XP checlist here:

It would be useful to try another NIC.

Thanks for pointing out the FAQ, I thought I found it in an obscure BIOS setting (wake on RING?) but no dice. I've tried different NIC in a different slot with same negative results.

I tried booting to safe mode and remove all NIC devices but was unable to remove my old NIC "ADMTek AN983 based ethernet adapter - Packet Scheduler Miniport" due to error: Failed to uninstall, device may be required to boot up computer. What gives with that?

I can ping localhost but cannot ping by hostname - strange? I'm going through rest of FAQ and MS checklist now. Thanks for assistance.

I think we've significantly narrowed it down. Repeated warning (red) messages show up in the Event Viewer on each reboot:

(1) Event ID: 7001 & 7000 "The DHCP client service depends on the SYMTDI service which failed to start due to invalid drivers"

(2) Event ID: 10010 "The server {hex code} did not register with DCOM within requested timeout"

I'm having a hard time chasing down the error codes listed in the Microsoft Knowledge Base - suggestions?

If you're upgrading from NAV 2002 or SystemWorks 2002 you had better plan on FULLY uninstalling the NAV product and not just by normal means.

THERE IS A SERIOUS BUG FROM SYMANTEC AND YOU'LL LOSE YOUR DHCP CAPABILITIES IF THESE STEPS AREN'T FOLLOWED! Do I make myself clear?

Go Check out http://www.bl.com/moshe/text/quiddities/norton_errors.html for full details, this one bit me in the ass and took me hours upon hours to straighten everything out.

Take the 5 minutes to do this right and you'll be ok.
