Is this from a client machine or on the server itself?

Also to add to @DaniSQL answer.. If you are connecting from remote machine, ensure, that the TCP/IP protocol is enabled in the Sql Server configuration manager.

Make sure that the port the Client and SQL Server are communicating over (default 1433) is open if there is a firewall between them.
