I guess you're using the server in a workgroup network. You cannot connect to the server in windows authentication mode. You must install the server in mixed mode and login using an account name (sa or other) and password.

use
server=MACHINE_NAME\INSTANCE_NAME; uid=sa; pwd=xxx;

There are 2 other things you must do before connecting
1) Enable sql browser service
2) Go to Configuration Tools->SQL Server Configuration Manager
Select
SQL Server Configuration->Protocols for [INSTANCE]
and enable TCP/IP (& restart the server)

==============================
However, if you're on a domain network & you have installed the SQL Server on the domain controller, you may login using windows authentication after adding logins.
To add logins, you may use
CREATE LOGIN [MACHINE_NAME\USER_NAME] FROM WINDOWS WITH DEFAULT_DATABASE=[master]

Check if there is login and password for that PC.

If yes then include the UserName and Password in the connection string

Put User ID=sa;

ConnectionString is missing userID, password and providername attributes.

connectionString="Data Source=192.168.1.2:1433;Initial Catalog=test;Integrated Security=True;Trusted_Connection=True";User ID=user;Password=pass;providerName="System.Data.EntityClient"
