Can’t connect to the Internet using LAN Cable on Windows XP

Hello there,
I can't seem to connect to the internet using my LAN cable on my Windows XP. I have searched for solutions from other forums and they all say that I should start a service that wasn't running (i.e. DHCP Client). I did that but I got this error:
“System error 1075 has occurred. The dependency service does not exist or has been marked for deletion.”
I read somewhere that NetBT should be cleared but when I did this, nothing happened. I also reinstalled Windows XP but it didn't work. The last thing I did was to try System Restore but that didn't work either. I did all these troubleshooting in Safe Mode.
I have run out of options. I need help. Thank you.
