You can check what port an SQL Server uses by connecting to it with SQL Server Management Studio while monitoring with [Process Explorer](https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer).
- Open SQL Server Management Studio. (Do not connect to the server yet)
- Open Process Explorer
- Find Ssms.exe in the process list and double click it.
- Select the TCP/IP tab
- In SQL Server Management Studio, connect to your server
- Back in Process Explorer, new connections will appear. Check the end of the remote address to find your port as `:port_number`.
