If you are using MS Windows, then use the Windows "Nslookup" command to explore whether your system can resolve the address of smtp.gmail.com . See https://technet.microsoft.com/en-us/library/cc725991.aspx

In particular, try

! nslookup -querytype=a smtp.google.com. ns3.google.com

If that succeeds then try also

! nslookup -querytype=a smtp.google.com.

which will give you a hint about whether your default nameserver is able to find the information. It is possible that somehow you have no nameserver configured or that the nameserver that you have configured is having problems reaching the appropriate name service. If you are connected to an internet provider it is common for your system to be configured to use DHCP that automatically configures a nameserver, but sometimes you need to configure your system according to static nameserver information provided by your internet company.
