Now you'll also need the normal server connection as before, which is still at TCP, but this time the port is unknown (since it's random). So for this, first you need to allow outgoing connections to the SQL Browser, which listens on UDP 1434. Basically, "dynamic port" means that the server listen on a "random" port each time it starts, and the SQL Browser service tells clients on which port is listening each instance (this is the default setup for named instances). The server itself only needs TCP access in the port it's listening to, so if you have a fixed port, you just open it (by default 1433 for a default instance) and you're good to go.īut since you're using dynamic ports, setup is a bit harder. The SQL instance on the remote server uses dynamic port 49365. Both the client and server are on the same domain. Microsoft SQL Server Management Studio (SSMS) is a software application developed by Microsoft that is used for configuring, managing, and administering all. Here you can check the column ProgramName. Once the result is displayed it, scroll down the resultset beyond SPID 50. First run following query in SQL Server Management Studio. First the easy part: the client doesn't needs any inbound connection, as it doesn't receive any connection (it makes them), so you can safely block everything inboud. Therefore, I would like to tighten my Windows 10/Windows Defender inbound and outbound firewall rules that I believe allow SQL Server Management Studio to talk to a SQL Server on a remote node. To identify which sessions are consumed by SQL Server Management Studio, we can take help of spwho2.
