Configure the PCs to obtain an address automatically from the DHCP server

Configure the router with the following IP information

FastEthernet0/0: IP Address: 172.17.13.1 Subnet Mask: 255.255.255.0 (NOTE: THIS IS NOT THE DEFAULT)

Click on the Settings button on the Config tab.

Click the Save button next to the NVRAM button to save your configuration on the Cisco Router. Failure to do this will cause your configuration to be lost when the router restarts

If everything has been configured correctly, you should be able to ping the DNS server from any of your PCs.

( I am still not getting any of the PCs to ping the DNS?)
