I trying to executing the following command 

ipconfig /renew

but, I get the following error

An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server. Request has timed out.

But, my DHCP service is already running.

enter image description here

I am trying to share my internet connection between my Laptop and Desktop via Ethernet Cable. Its not working and when I diagnose the connection I get this error - lan doesn't have a valid ip configuration.

How can I renew my IP?

Server is the DHCP server on your network and not the DHCP Client service. – Brian Oct 29 '12 at 12:15
umm, is it ok now? – iamcreasy Oct 29 '12 at 12:20
You say; "I am trying to run this command cause I am trying to share my internet connection between my Laptop and Desktop." How are you sharing the connection? – CharlieRB Oct 29 '12 at 12:27
@charlierb updated. What else do I need to add? – iamcreasy Oct 29 '12 at 12:43
Can you describe it better? Which computer has the Internet connection and how is it connected? Are you using a crossover cable or just a regular piece of Ethernet cable? Have you searched the Internet how to do this? – CharlieRB Oct 29 '12 at 12:49
