To enable remote connections on the instance of SQL Server 2005 and to turn on the SQL Server Browser service, use the SQL

Server 2005 Surface Area Configuration tool. The Surface Area Configuration tool is installed when you install SQL Server 2005.

You must enable remote connections for each instance of SQL Server 2005 that you want to connect to from a remote computer.

To do this, follow these steps:

If you are running SQL Server 2005 by using an instance name and you are not using a specific TCP/IP port number in your

connection string, you must enable the SQL Server Browser service to allow for remote connections. For example, SQL Server

2005 Express is installed with a default instance name ofComputer Name\SQLEXPRESS. You are only required to enable the

SQL Server Browser service one time, regardless of how many instances of SQL Server 2005 you are running. To enable the

SQL Server Browser service, follow these steps.

Impor tant These steps may increase your security risk. These steps may also make your computer or your network more

vulnerable to attack by malicious users or by malicious software such as viruses. We recommend the process that this article

describes to enable programs to operate as they are designed to, or to implement specific program capabilities. Before you make

these changes, we recommend that you evaluate the risks that are associated with implementing this process in your particular

environment. If you choose to implement this process, take any appropriate additional steps to help protect your system. We

recommend that you use this process only if you really require this process.

These steps apply to the version of Windows Firewall that is included in Windows XP Service Pack 2 (SP2) and in Windows

Server 2003. If you are using a different firewall system, see your firewall documentation for more information.

If you are running a firewall on the computer that is running SQL Server 2005, external connections to SQL Server 2005 will be

blocked unless SQL Server 2005 and the SQL Server Browser service can communicate through the firewall. You must create an

exception for each instance of SQL Server 2005 that you want to accept remote connections and an exception for the SQL Server

Browser service.

SQL Server 2005 uses an instance ID as part of the path when you install its program files. To create an exception for each

instance of SQL Server, you must identify the correct instance ID. To obtain an instance ID, follow these steps:

Note When you run the SQL Server Browser service on a computer, the computer displays the instance names and the

connection information for each instance of SQL Server that is running on the computer. This risk can be reduced by not enabling

the SQL Server Browser service and by connecting to the instance of SQL Server directly through an assigned TCP port.

Connecting directly to an instance of SQL Server through a TCP port is beyond the scope of this article. For more information

about the SQL Server Browser server and connecting to an instance of SQL Server, see the following topics in SQL Server Books

Online:
