Windows DCOM on the Agent Manager Console computer uses RPC dynamic port allocation to randomly select a port number ranging from 1024 to 65535 for communication with the central computer. The Agent Manager Console uses this port to discover the Windows Distributed Component Object Model (DCOM) listening port on the central computer.
If you use a firewall to separate the database server from the central computer, the database server cannot communicate with the central computer unless you restrict RPC port usage to a specific number of ports higher than 1024 and then open those ports.įor more information about configuring MSDTC and RPC port usage, see Microsoft Knowledge Base Articles 250367, 300083, and 826852.īy default, the central computer uses this port to connect to the Agent Manager Connector on the Sentinel server. MSDTC on the database server computer uses RPC dynamic port allocation to randomly select a port number ranging from 1024 to 65535 for communication with the central computer. The database server uses this port to discover the Microsoft Distributed Transaction Coordinator (MSDTC) listening port on the central computer. If using a SQL Server instance, the browser service uses UDP 1434 to identify the port for the named instance. Instances use alternate ports configured during installation. This port is the default port for Microsoft SQL Server. By default, the central computer uses this port to connect to the OnePoint database on the database server.
