Windows 防火墙系统用于阻止对计算机资源进行未经授权的访问。若要通过该防火墙访问 Analysis Services的实例,必须将防火墙配置为启用访问。有很多可用的防火墙系统。如果要运行 Windows防火墙以外的防火墙,请查阅防火墙文档以获得专用于您系统的信息。以下信息专用于 Windows 防火墙。
您必须将 Windows防火墙配置为使经过授权的用户或计算机能够访问相关的端口,包括将 Analysis Services 配置为使用特定的 TCP/IP端口。Analysis Services 的默认实例使用端口 2383,但可以更改。Analysis Services的命名实例使用动态端口。有关如何配置使用特定端口的详细信息,请参阅如何配置服务器以侦听特定 TCP 端口(SQL Server 配置管理器)。如果只运行 Analysis Services 的默认实例,则可选择使用 SQL Server Browser 服务。若要使用 SQL Server Browser,必须打开 UDP 端口 1434。
注意:
默认情况下,Microsoft Windows XP Service Pack 2 将启用 Windows 防火墙,这会关闭端口2383,从而防止 Internet 计算机连接到您的计算机。只有重新打开端口 2383,才能使用 TCP/IP 通过 Internet连接到 Analysis Services。有关详细信息,请参阅 Windows 文档。

                                                        配置 Windows XP 防火墙或 Windows Server 2003 防火墙                       
                                 
注意:
如果要运行 Analysis Services 的命名实例,必须确保该命名实例的端口号作为异常列出,SQL Server Browser 服务也作为异常列出。

                         

               
                                                        打开端口以使 SQL Server Browser 服务可用                       
                                 
注意:
单击“Windows 防火墙”对话框中的“添加程序”以设置其他选项,例如授予访问特定程序的权限和限制访问某些 IP 地址或网络子网。有关详细信息,请参阅 Windows 文档。

INF: TCP Ports Used by OLAP Services when Connecting Through a Firewall[url=#appliesto]View products that this article applies to.[/url]
Article ID:301901
Last Review:October 26, 2007
Revision:3.3

This article was previously published under Q301901
SUMMARYFirewalls are frequently used for security, and many firewalls are set to disable the TCP ports that are used by Microsoft Analysis Services 2000 and Microsoft OLAP Services 7.0. Consequently, when you deploy OLAP Services clients over an intranet, extranet or internet, you should consider the TCP ports that are used by both the server and the client.
MORE INFORMATIONOLAP Services 7.0 uses TCP ports 2393 and 2394. Microsoft has also reserved UDP ports 2393 and 2394; however, UDP ports 2393 and 2394 are not used by OLAP Services. Analysis Services uses TCP port 2725. For backward compatibility, Analysis Services uses TCP ports 2393 and 2394 when connected with an OLAP Services 7.0 client.

Connections that use HTTP were introduced with Analysis Services. This connection method allows the PivotTable® Service to tunnel through firewalls or proxy servers to the Analysis Services server. When connecting to Analysis Services by using HTTP, the connection occurs through Microsoft Internet Information Services (IIS). The port used during connection is defined by the default port of the Web site. In most cases, the default port of the Web site is set to 80 (or 443 if Secure Sockets Layer [SSL] is used).

For additional information about connecting to Analysis Services 8.0 by using an HTTP connection, refer to the "Connecting Using HTTP" topic in SQL Server Books Online.
