Where I mentioned, make sure auto-detect settings is NOT enabled.
Disable WPAD (Web Proxy Auto-Discover) in Internet Explorer:
- Internet Options -> Connections -> LAN
- Disable 'Automatically detect settings'
Regarding WPAD, read:

I have had that option disabled for many years. I don't use web proxies
and don't remember ever having an ISP that hooked me up to one. I never
saw a need to enable this option (at home) but then I've never been on a
3rd tier provider/domain, either. There is no point to do the multitude
host searches trying to find a WPAD server when there isn't one. It can
cause a "gateway timeout" error in IE because it took too long to find a
WPAD server (that does not exist). The WPAD functionality is documented
in the IEAK (Internet Explorer Administration Kit).
Have you tried using a different CAT5 cable(s)? One of them might be
bad. Do you see the green Link LED lit up on both ends where the cable
is connected (to show hardware-level linking between the devices)? Have
you unplugged the cable from the working desktop and connected that
cable to the laptop to retest? Has the laptop been rebooted yet (and
not just put into hibernate mode when closed)?
How is Internet connectivity achieved? Dial-up? Broadband (cable or
DSL)? Satellite? Wired or wireless from host to access point or
router? If wireless, did you configure the access point or router to
permit a connection from that laptop?
Is the problematic host directly connected to the [dialup/cable/dsl]
modem, or does it go through a hub, switch, gateway host, or router? If
you use a router, can you connect to its internal web server (for its
setup screens)? Usually the router's IP address is 192.168.1.1 (so use
http://192.168.1.1 in a web browser) but you'll need to check the
documentation for your router to make sure.
If you are not using a NAT (network address translation) capable router
to connect multiple hosts to the same ISP, just how are you connecting
them to your ISP? Are you swapping the cable between the two hosts?
Each has a different MAC (media access control) hardware address.
Awhile ago (for my ISP, like over 3 years ago) they required
provisioning of their service to a specific MAC address. If you
switched to a different host, it had a different MAC address and you had
to call it to get reprovisioned. After the ubiquitous presence of NAT
routers by home users, most ISPs dropped that requirement and will let
any device having any MAC address connect to their service (but may
probably still require that only one MAC address be connected at a time
from a particular node because you are only paying for one-device access
so you still need a NAT router).
Is a network adapter listed in Device Manager? Does it have a yellow
exclamation icon next to it?
There is way too much unknown about your particular network
configuration to make further guesses. You'll have to tell us what it
is.
