Can't obtain IP-address (strange behaviour)

[petersson]

ng,

i've set up a firewall on a dedicated box (linux/IPcop distro) and now
i'm trying to connect a few XP boxes. The firewall is currently a
subnet on our existing LAN. So i snatch the LAN-cable from my collegues
laptop, replacing it by the cable from the firewall. A few seconds
pass, and the new IP-address emerge (IPCONFIG).

Now for the (not so!) funny part... I take the *same* cable from the
firewall and stick it into my own laptop. And nothing happens. IPCONFIG
says 'Media Disconnected' so all /RELEASE, /RENEW stuff have no effect
('No operation can be performed on Local Area Connection while it has
its media disconnected'). The NIC diode on the firewall is compleatly
dead. The strange thing is that my laptop works fine on our existing
LAN (and, also at home, where i have a small network). I'm currently
using my computer on four different networks, with no problems on any
of them...

All XP-boxes at our office (including my own) are set to obtain network
settings automatically. They have DHCP and LMHOSTS enabled. The NetBIOS
settings are set to 'default' (i've tried 'enable', with no effect).

I've tried:

* ipconfig /flushdns
* nbtstat -RR
* netsh int ip reset c:\temp\resetlog.txt
[http://support.microsoft.com/default.aspx?scid=kb;en-us;299357]
* downloaded and ran 'WinSock XP Fix 1.2'
[http://www.majorgeeks.com/download4372.html]
* Tried shutting down my own personal firewall (ZoneAlarm).
* On the Linux/Firewall, I've tried serving IP-addresses by DHCP and
by MAC-address.
* Harmonizing the services on my box with the ones on the working box.
* Setting the 'Linkspeed' property on my NIC to 'Auto Detect'.
* tail -20 /var/log/messages shows nothing. Not even an error...

The gyus back in the linux ng:s said it's probably a client settings
problem. So here i am... Someting tells me that it might be a service
that's not starting?

I use:
* XP Pro (ver. 2002 - sp1)
* Toshiba Satellite A series, Satellite A30

I'm getting desperate. Plz advice.

TIA

This is a NIC/hardware problem, not anything involving DNS, NetBIOS,
TCP/IP, etc. Try explicitly setting the proper speed and duplex modes
for the NIC (e.g. 100 Mb, full duplex). Autosensing doesn't always
work. Try a different firewall port.
