To install Dynamics GP on a network, the following are required:
Domain: Domain is listed as a requirement in the Dynamics GP 2013 installation manual, and Peer to Peer environments, previously supported with Dynamics GP, are no longer anywhere in the documentation. This requirement means that all client workstations and servers (including the SQL Server, Remote Desktop Services server, and Web server) must belong to a domain.
Network Protocol: TCP/IP is the only required and supported protocol for Dynamics GP. While Named Pipes can sometimes be used successfully, it is not required and may not be supported.
Name resolution: Name resolution needs to be used so that each computer is identified by a unique host name. Internally handled name resolution is recommended for the most reliable Dynamics GP performance.
