Connect To Internet But Not To Lan

Colleagues,

I have a fresh installation of WS2013E and it connects to the Internet but not to the LAN and so I cannot take advantage of the home network resources I have (such as a network printer, etc.).

In the Network and Sharing Center it says that the active network is the domain network the OS created when it installed. I am not familiar with networks and/or domains, but everything else works.

So, my question is: How can I make the server connect to the LAN?

Thank you all in advanced.

Regards.
