Hello

I am new to this but I am trying to set up T1 on a Cisco router 1841. I configured the s0/0 with the IP address provided by TW telecom
they also gave me a block address of 173.226.197.156/30

I configured fa0/0 interface of the router with 173.226.197.157

I also configured dns and nat

below is a copy of the config but I'm still not getting any connection, this is what I get when I ping google.com

% Unrecognized host or address, or protocol not running.

Wrong forum, but where is your default route? Assuming your ISP's site of that serial is 74.202.214.153:
ip route 0.0.0.0 0.0.0.0 74.202.214.153
or
ip route 0.0.0.0 0.0.0.0 serial0/0/0
 
Ditto on the default router.

Plus when you test, always test a ping to a known externally pingable IP before you worry about name resolution. If you'd tried to ping an external IP it would have failed, so you would have known that it had nothing to do with DNS.
