Sounds like the wrong gateway and/or subnet mask on PC2. It could also be as simple as a firewall issue not allowing icmp on PC2.

ip and DG are right, and firewall disabled on pc2.but still cannot access.

Is there a "second" firewall still enabled?
e.g.: Turned off Norton firewall, but Windows Firewall was also turned on, and remains on unknown to the user.
I know you don't want to run two simultaneously, but I have seen users do this (knowingly or unknowingly), so I thought I'd ask?
Is there any device (switch, transparent firewall) between the router and PC2 enforcing any ACLs?

fe0/0-10.116.144.1
fe0/1-10.16.144.17.
Is fe0/1 address a typo above as your "sh ip int br" output shows fe0/1 having an address of 10.116.144.17 not 10.16.144.17 ie.
FastEthernet0/0 10.116.144.1 YES NVRAM up up
Serial0/0 10.116.145.101 YES NVRAM down down
FastEthernet0/1 10.116.144.17 YES NVRAM up up
What subnet masks are you using on these interfaces and on the PC's ?
