Īlthough an application might be listening on a specific port, connections will not succeed if a firewall is blocking access. Verify the port by using SQL Server Management Studio and connect to an Analysis Services server in this format. Run netstat -ao -p TCP from the command line to view the TCP port information for that PID. Start Task Manager and then click Services to get the PID of the MSOLAP$InstanceName. You can determine the actual port number in use by a named instance by doing the following: The MSOLAP$InstanceName service determines which port to use when it starts up. If Port is set to 0, the service is listening on port 2383 if it is the default instance or on a dynamically assigned port if it is a named instance.ĭynamic port assignments are only used by named instances. If Port is set to a positive integer, the service is listening on a fixed port. Port settings are specified in the msmdsrv.ini file and in the General properties page of an Analysis Services instance in SQL Server Management Studio. SQL Server Setup does not perform this step for you. You must manually open a port in the firewall to allow inbound requests to Analysis Services. On the Microsoft Windows operating systems that are supported by SQL Server 2017, Windows Firewall is on by default and is blocking remote connections. Check port and firewall settings for Analysis Services Use a fixed port for a default or named instance of Analysis Servicesįor more information about the default Windows firewall settings, and a description of the TCP ports that affect the Database Engine, Analysis Services, Reporting Services, and Integration Services, see Configure the Windows Firewall to Allow SQL Server Access. Port configuration for Power Pivot for SharePoint Port configuration for an Analysis Services cluster This topic contains the following sections:Ĭheck port and firewall settings for Analysis ServicesĬonfigure Windows Firewall for a default instance of Analysis ServicesĬonfigure Windows Firewall access for a named instance of Analysis Services See Configure HTTP Access to Analysis Services on Internet Information Services (IIS) 8.0. You can then set up multiple HTTP endpoints on whatever ports you choose. If you have specific multi-port requirements, consider configuring SQL Server Analysis Services for HTTP access. On computers having multiple network cards or multiple IP addresses, SQL Server Analysis Services listens on one TCP port for all IP addresses assigned or aliased to the computer. Only one TCP port can be used by an SQL Server Analysis Services instance. For more information review SPN registration for SSAS instances listening on fixed ports You cannot use a non-default port for Analysis services if you need to connect to your instance using Kerberos. See SQL Server Business Intelligence in Windows Azure Virtual Machines.Īlthough the default instance of SQL Server Analysis Services listens on TCP port 2383, you can configure the server to listen on a different fixed port, connecting to the server in this format. As an add-in to SharePoint, the service uses ports configured for SharePoint and makes only local connections to the SQL Server Analysis Services instance that loads and queries Power Pivot data models.įor SQL Server Analysis Services instances running on Windows Azure Virtual Machines, use alternate instructions for configuring server access. ![]() As with other SQL Server Analysis Services named instances, create an inbound rule for SQL Server Browser service on TCP 2382 to allow access to Power Pivot for SharePoint.įor Power Pivot for SharePoint 2010, do not open ports in Windows Firewall. Inbound requests to the named 'Power Pivot' instance originate from SharePoint web applications over a network connection, requiring an open port. In Power Pivot for SharePoint 2013, the SQL Server Analysis Services instance is external to SharePoint. ![]() Open TCP port 2382 when installing SQL Server Analysis Services in SharePoint mode to support Power Pivot for SharePoint 2013. As the discovery service for Analysis Services, SQL Server Browser service listens on TCP port 2382 and redirects the connection request to the port currently used by SQL Server Analysis Services. Named instances use dynamic port assignments. Open TCP port 2382 when installing a named instance. Open TCP port 2383 when installing a default instance or creating an SQL Server Analysis Services failover cluster. Most installations will require that you create at least one in-bound firewall rule that allows connections to SQL Server Analysis Services.įirewall configuration requirements vary depending on how you installed SQL Server Analysis Services: An essential first step in making SQL Server Analysis Services or Power Pivot for SharePoint available on the network is to determine whether you need to unblock ports in a firewall.
