SQL Server 2012 installation error withA network-related or instance specific error occured while establishing a connection to SQL Server.
The server was not found or not accessible.
I've never heard of this error during an initial installation before. The error itself is a common one, but not during installation.
Also, your question at http://www.sqlservercentral.com/Forums/Topic1759067-3411-1.aspx say's you're trying to install SQL 2014. This one says you're trying to install SQL 2012 and you posted it in a SQL 2014 forum. Are you trying to install SQL 2012 on a server with SQL 2014 already installed?
Between this question and your other one , I also have to ask where you got your installation media.
