It refers to XP but the same applies to Vista. As chub_tor suggested, remove USB wireless/wired adapters.
Hit f8 repeatedly when booting, when the menu appears select Last Known Good Configuration.
You can try hitting F8 at boot as before and choose Safe Mode to gather some information - don't choose Safe Mode with Networking. If you can get in using that method, you could try System Restore.
If that doesn't work and it's a network device driver error (which it appears to be) you'll need to download the latest drivers for the problem device on another machine ready to install when you remove or uninstall the device on your own PC ready to update. Can you give more information about your PC? Make/model etc
