This listener service responded to client requests with the names of the installed instances , and the ports or named pipes used by the instance 此侦听器服务用已安装的实例的名称以及实例使用的端口或命名管道来响应客户端请求。
Any component that tries to connect to a named instance without fully specifying all the parameters , such as the tcp ip port or a named pipe 任何组件在未完全指定所有参数（例如tcp / ip端口或命名管道）的情况下尝试连接到命名实例。
Sql server browser reads the registry , identifies all sql server instances on the computer , and notes the ports and named pipes that they use 它将读取注册表，标识计算机上的所有sql server实例，并注明它们所使用的端口和命名管道。
If the sql server browser service is not running , you can still connect to sql server if you provide the correct port number or named pipe 当sql server浏览器服务不在运行时，如果您提供了正确的端口号或命名管道，则仍然可以连接到sql server 。
Sql server browser reads the registry , identifies all instances of sql server on the computer , and notes the ports and named pipes that they use Sql server浏览器将读取注册表，识别计算机上的所有sql server实例，并注明它们使用的端口和命名管道。
If the sql server browser service is not running , you are still able to connect to sql server if you provide the correct port number or named pipe 当sql server browser服务不运行时，如果您提供了正确的端口号或命名管道，仍可以连接到sql server 。
The network library on the client application then completes the connection by sending a request to the server using the port or named pipe of the desired instance 然后，客户端应用程序中的网络库将使用所需实例的端口或命名管道向服务器发送请求来完成连接。
Ensure that remote connections are enabled at the publisher and at the subscriber tcp ip or named pipes and that the sql server agent service is running 请确保在发布服务器和订阅服务器上已启用远程连接（ tcp / ip或命名管道） ，并且sql server代理服务正在运行。
The network protocol support for user instances is only through local named pipes , which implies that a user cannot connect to a user instance from a remote computer 仅通过本地命名管道为用户实例提供网路协议支持，这意味着用户不能从远程计算机连接到用户实例。
If the sql server browser service is not running on the server , you must provide a connection endpoint tcp ip port or named pipe to connect to a named instance 如果服务器中没有运行sql server browser服务，则必须提供一个连接端点（ tcp / ip端口或命名管道）以连接到命名实例。
