Chuck helped me get my network running a year ago but I have got a new
computer and now I can't get it to work.
The network couldn't be simpler. The new Dell desktop is connected to the
Internet through a USB ADSL Modem connected to the phone line. Works fine.
The other computer on the network is a Dell Inspiron laptop. They are
connected with Ethernet cables through a Netgear 4 port router. The set up
has worked fine for over a year and the hardware and cables are all fine as
far as I can see. The problem seems to be that the desktop is not assigning
an IP address to the laptop and can't see why or how to cure it.
The desktop has Windows XP Media Center and the laptop Windows XP SP2.
Ipconfig on the desktop is as follows -

It looks awfully like the problem is with DHCP not enabled on the ADSL2
adapter. If so, how do you enable it ?
Can Chuck or anyone else tell me what is wrong ?

You're right: the desktop isn't assigning an IP address to the
laptop, as shown by the laptop's Ethernet adapter having an
Autoconfiguration IP address.
"DHCP Enabled" means that a network adapter is configured to obtain an
IP address automatically. It doesn't mean that the adapter is
configured to act as a DHCP server. So neither adapter on the desktop
has to have DHCP enabled. The Ethernet adapter has a static IP
address of 192.168.0.1, probably because you enabled Internet
Connection Sharing on the ADSL2 adapter The ADSL2 adapter has a
static IP address assigned by bluewin.ch.
It's the laptop's Ethernet adapter that has to have DHCP enabled, and
it does. So why isn't it getting an IP address? Here are some ideas:
1. On the desktop, disable ICS and then re-enable it. Then, disable
and re-enable the laptop's Ethernet connection.
2. Use the Netgear router as a network switch only, bypassing its
routing capabilities:
a. Disable its built-in DHCP server.
b. Connect both computers to its LAN ports.
c. Don't connect anything to its WAN (Internet) port.
3. Try different network cables on both computers.
4. Download and install the latest Ethernet adapter drivers. Since
the laptop's Internet connection isn't working, download its driver on
the desktop and transfer it to the laptop using a CD, USB flash drive,
etc.
5. Automatic sensing of speed and duplex modes sometimes fails.
Manually configure both computers' Ethernet adapters to the same
settings. Start with 10 Mb / half duplex. If that works, try 100 Mb
/ full duplex.
