One computer is having a problem connecting to the Internet

Problem: One computer has no Internet access

Solution: there are many things that can cause this problem. Here is a list of items to check:

1. Try rebooting the computer
2. Do an IPConfig and make sure you have a valid IP Address that is within that subnet for that LAN. If you do not have a valid IP Address, try releasing and then renewing the IP Address. If you still do not get a valid IP Address, check the physical connection and make sure the DHCP Server isn’t having a problem.
3. Can you ping the default gateway from this computer
4. Test and see if you can ping 4.2.2.2
5. Test and see if you can ping google.com
6. Try a different browser
7. Make sure your hosts file has not been hijacked by a virus
8. Check for spyware
