Enabling Server Connectivity

Using SQL Native Client’s Development Features

Understanding Client Software Connectivity

S

QL Server follows Microsoft’s philosophy of “secure by default” and reduces the surface area of

the application. The initial installation enables local access only and no network connections

for express and developer additions. (That is, remote client applications cannot connect.)

Chapter 3, “Installing SQL Server” discusses SQL Server surface area confi guration as part of the

installation process.

The Server Confi guration Manager tool installed with SQL Server can nearly always communicate

with SQL Server, so you can confi gure the server connectivity options and open the server up for

network access. The connectivity relies on open paths between the client and server machines. As

Windows Server by default comes with a fi rewall enabled, there will often be issues.

With network access allowed on the SQL Server, SQL Server provides clients with a new means to

access functionality and features through the SQL Server Native Client (SNAC).

Before getting into the SNAC, you must enable network access for the new server.
