First, I'd look for a LSP / Winsock / TCP/IP problem. With Vista this is a bit
simpler than with XP.
Then look for a misbehaving personal firewall. Any anti-malware software too.
Finally, I'd check for physical network problems, and the network device
drivers. Is the laptop under warranty? The fact that the laptop can
communicate with the desktop may or may not rule this out. Ditto both Ethernet
