Bizzare Network problem on Latitude C400
Hi, having connection problems on a Dell Latitude C400.
Laptop connected to business network, connection icon shows cable connected.
However machine cannot see network. Machine has given itself a 169 IP address.
Bypassed Network card and used plugin card, exactly the same.
Dell came and replaced motherboard, same problem
Re formatted drive and re installed windows 2000, same problem.
Connected Laptop directly to Switch, same problem.
All drivers correct and working fine in device manager.
I'm stumped, does anyone have the slightest idea what the problem could be? I'm tearing what's left of my hair out.
Thanks in advance to anyone who takes the time to reply!
regards
Simon

The realy strang thing is, that the Laptop was running perfectly with the network when i received it preinstalled from Dell. But i had to set it up completely new, and since then this problem occurs...

I can't get access to a Novell network. Same conditions as at Simons problem. Connection showed in the task bar, but no real IP or physical adress can be seen in the Broadcom controls suite.
My solution (not good but working...):
For a connection to a Novell network i have to install EACH time after rebooting my Latitude D400 the device driver R61662 (Broadcom 570X driver)
After the installation (do not reboot !!!!!!!!) the connection to the network will be cut and reconnected. And then the network is working.... until the next reboot...

One (#1) just had the motherboard replaced for a video problem, except now it detects the network but it cannot get an ip from from the dhcp server. The computer is running Windows 2000, I have tried updating the network drivers, removing/readding it, and I even tried a winsock fix. Nothing works.
I was prepared to call dell about the problem, but first I thought I should test it with a known working system. So I swapped hard drives. The other c840 (#2) has Windows XP. I swapped the drives...now both of them don't work. Same issues as before.
Ok, maybe it is a Windows 2000 issue, so I swapped the hard drives back. Now both of them are exhibiting the same behavior.
I am going flash the BIOS for a last-ditch effort to see if this fixes the problem, but I'm not sure it will. Thanks for any assistence. This behavior is just odd...we service almost a hundred of these laptops, and I've never seen such an weird problem as this before.
