I got them ol' DHCP blues

My PC has completely lost interest in automatically obtaining an IP address from any network, by any method.

My Toshiba Satellite Pro has been my tireless servant for over 3 years. Last week, while plugged into my ADSL router via an ethernet cable, I went to get a cup of tea. When I got back, 5 minutes later, I had 'limited or no connectivity' on the network. Restarting the router had no effect, restarting the PC had no effect. I can assign an IP address manually, and connect to the internet with ease and joy via both ethernet cable and PCMCIA wireless card and USB wireless dongle thingy. The moment I entrust the computer with the oh-so-difficult task of attempting automatic IP acquisition, the taskbar icon hangs at 'acquiring network address' and then gives up some minutes later.
Some additional facts:
There's another computer on the same network, it has no problem getting an automatic IP address. DHCP is enabled on the router, there's a wide enough range of available addresses, and it's been working fine for many months prior to this.
I've tried the PC on 3 different networks, with the same result - automatic is hopeless, manual is ok.
My DHCP service is active on the PC, and is set to automatically start on start-up.
WinSockFix does nothing to help.
Enabling NetBIOS over TCP/IP does nothing to help.
Google tells me that seemingly lots of other people have had similar problems, but either only with wireless, or because they forgot to enable DHCP on their router, or some other fairly straightforward thing that doesn't seem to apply to me. And lots of advice online has been stuff like 'try restarting the computer', or 'make sure your router is switched on'.
This is driving me insane, and while I can access the internet at home, because I know the right DNS gateways to use for manual DHCP, it means I can't use the laptop away from home.
What have I missed? Can anyone help?!
