Kindly update the drivers of the LAN card
One possible reason for "limited connection" is that the network driver was unable to complete the DHCP handshake and has assigned an address to itself that can't really talk to the network. I'm not sure KNOPPIX how would fix this, although KNOPPIX has a very good reputation for hardware detection and support -- but it's a live Linux CD. Booting to it, you might be able to see that your hardware successfully connects to the network, but that would not directly help solve the problem you're having under windows other than assure you that the problem is most likely with your Windows network driver.

Can you say more about your environment and whether this is a new problem you're experiencing with a system that has worked in the past or if there has been some change.

One quick thing is to try a different Ethernet cable. Might be a bad cable or loose end.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

A connection limited message, so i'm you are using Windows OS.  if your network is small and simple then step 1 & 2 should do it for you. If it's a bit more advanced then continue to 3 &4. This is what i would do if i were you:

1. Use the same connection with a known working device. It could be another pc, printer, phone, laptop, etc. If it works with it then you know the issue lies on the pc, if it does not work then

2. Try a different eithernet cable as suggested by Willian, if it does not work then

3. Test the network jack (assuming that's how you are connected),  you need tools for this. if it does not work then

4. make sure you are patched in on the right switch port. It may be you are connected to an unconfigured port.

Also try TCP/IP Reset to see if that is the issue.

Open cmd.exe with Run as Administrator
Then  netsh int ip reset c:\resetlog.txt
Also, ipconfig /flushdns followed by net stop dnscache followed by net start dnscache
Then restart the computer
