connectionString local network Asp.Net MVC SQL SERVER

I'm trying to connect a bank in my application, which is networked, so I put the following Path:

<connectionStrings>
    <add name="smc" connectionString="Data Source=192.168.0.29; Initial Catalog=nomeDoBanco; User=sa; Password=senhaDoBanco" providerName="System.Data.SqlClient" />
  </connectionStrings>

Application Error:

[Win32Exception (0x80004005): Access Denied]

[SqlException (0x80131904): network or instance-specific error establish connection to SQL Server. The server was not found or it wasn't accessible. Verify that the instance name is correct and if SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - could not open a connection to SQL Server)]

Error when trying to access from manager

However, da error. Does anyone know if I need to report something else in the Data Source, or if I have to set up something in the bank?
