TCP 2382
Synopsis
- TCP port 2382 is used by Microsoft SQL Server Browser service for Analysis Services (SSAS) redirection.
- Clients connect to 2382 to learn the actual TCP port of the SSAS instance; the default SSAS instance typically uses TCP 2383, while named instances use dynamic ports.
- Real-world clients that rely on 2382 include Microsoft Excel PivotTables connecting to SSAS cubes, Power BI Desktop and the On-premises data gateway, SQL Server Management Studio (SSMS) when connecting to Analysis Services, and Tableau connecting to Microsoft Analysis Services.
- On servers running SSAS, the “SQL Server Browser” service listens on TCP 2382 to provide this redirection.
- Blocking 2382 often breaks connections to named SSAS instances unless clients are configured with the specific target port.
- Security note: attackers sometimes scan 2382 to discover SSAS instances and gather service information, but the port itself is not commonly associated with a specific widespread exploit.
