Can ping dns server ip address from 3750 switch but not google.com

Hello,

I can ping the dns server ip address from 3750 switch but I cannot ping anything like google.com or yahoo.com, etc. I have ip domain-look up enable and the ip name server commands are configured correctly.  Does not seem no access list is blocking this.  Also these swithc is connected to a core switch and the core switch is able ping google.com.  Does anyone what could cause a reply with dns ip address but not yahoo.com from switch?

 

Thanks,
