My PC cannot access FQDNs through Cisco 1841 HWIC 3G Gateway

I have set up a Cisco 1841 with the HWIC-1T    as a gateway.  I have one PC on the LAN side and can ping outside public IPs with no issues.  However, when I try to ping or connect via HTTP to a domain name, it won't resolve the IP address.  The Router config and interface status are below:

Router#sh ip int b

Any interface listed with OK? value "NO" does not have a valid configuration

Interface                  IP-Address      OK? Method Status                Protocol

Router#

Do an ipconfig /all on the PC to ensure it is being issued the DNS server address via DHCP on the router.

After you have verified this, if the DNS server IP is present and correct;

Conduct an 'nslookup' from the command line

Check the server listed is correct, else type 'server 208.67.222.222'

Then type 'www.google.com.au' and see if it resolves in an NSLookup.

Let me know the results of the above.  WS-X45-SUP7L-E     Thanks
