Resolved Some PCs show limited or no connectivity

HI i just recently extended my network to the next block. I am able to connect to internet and all. But i am facing an issue with 2 laptops which are showing limited or no connectivity no matter which port on the switch it is we use to connect to the network. I am able to connect to the network through wireless. When i am trying to use LAN then its showing limited or no connectivity. I tested the ports on the switch with another laptop its getting connected to the network through lan.

I need some help.

The network settings are i use obtain ip address automatically and i give the dns server addresses in the tCP/ IP properties.

 

I got it resolved just by increasing the DHCP server leasing range.... It was limited to 10 ip addresses and i increased it to 30 now its working absolutely fine
