    We have a SQL Server 2005 default instance set up on a server. I was requested to install a named instance and to use a static port number. What is the benefit of changing the port number to be diferent and to be static? I have never done that before. I always took the defaults.

    SQL Server is a Winsock application that communicates over TCP/IP using the sockets network library. The SQL Server listens for incoming connections on a particular port; the default port for SQL Server is 1433. The port doesn't need to be 1433, but 1433 is the official Internet Assigned Number Authority (IANA) socket number for SQL Server. See this articl3e http://technet.microsoft.com/en-us/library/bb726981.aspx on how TCP/IP interacts.

    I have learned that they are changing the port number for the JAVA programmers.

    That is good to seperate the applications based on the ports.
