Hi Alan,

I set the ifcfg-eth0 as you suggested with the following:

DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes

Then I ran the ifup command, with the below result:

[root@xxxxxxx root]# /etc/sysconfig/network-scripts/ifup eth0
Determining IP information for eth0... failed.

Not terribly encouraging.  Any ideas why it's died?

In Mandrake control panel the network connection properties say:

DHCP
current IP address 192.168.1.3
netmask 255.255.255.0
gateway 192.168.1.1 (router IP address)

One thing I *think* is wrong is that the DNS server points to the router
also.  Would that be so DNS requests go to the router and then to the
external DNS servers?  If so it's obviously OK.

Incidentally as soon as the Linux machine booted up, the laptop
currently running Windows 2000 complained that another machine was
trying to use the same IP address.

Kind regards,

Julian
