PCs with XP can have FW that prevent unsolicited pings , check and configure as necessairy

thanks for the response,i moved pc 2 to where pc1 was and it worked.transferred pc1 to pc2,could not ping yet,am having same problems on three other routers.can i get a solution pls

firewall disabled on the pcand cannot ping yet

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 ?

Jon

is a typo,

pc1--Ip 10.116.144.5

DG 10.116.144.1

SM 255.255.255.240

pc2-ip 10.116.144.21

DG 10.116.144.17

SM 255.255.255.240.

3) post output of "ipconfig" on each PC.

Jon
