it's DHCP; because without setting a server when you try to access peer to peer connections you must have to access by using internet; only way is DHCP protocol will help you to give Dynamic ip address and etc...
ip
Create a workgroup in TCP/IPIf you log in through the server, then the workgroup is set up on the server and each computer joins via the "system properties/join a domain" buttons. If you do not log in through the server then just create a workgroup through the same process as above. The switch might have a setting to set a workgroup name as well, especially if it is being used as a TCP/IP DHCP server.
server
Configuring a workgroup is easy - give the workgroup and name and use that name in the workgroup section for the computer identification. The other choice is for a client-server (domain) based network. Therefore you only have two choices for computer identification; either as a workgroup or as a domain (client/server).
a workgroup is the name for a group of computers in a network environment. Under windows this is a name you can choose yourself for each computer. The computers who have the same workgroup name can easily exchange information through the network. A workgroup does not require a central server. a domain is basically an advanced workgroup where every computer & user requires authentication (login/pass for instance), maintained by a central server(s). workgroups are generally used in residential houses (for ex. to exchange data between 2 PCs), whereas domains are generally used in companies.

Default Server Setting
SMB (Server Message Block)
its just called a network enabled computer or server or a workgroup and this if it configured to work
If the server does not have Online Mode enabled, users without premium accounts will be allowed to join. You can change the setting by editing the file server.properties with any plain text editor such as Notepad, then restarting the server.
The Peer-to-Peer networking model.
Make sure your workgroup is the same and use peer to peer (server asigned ip address) on all machines
