SQL Server – performance and other stories: SQL Server Port - How

Open port 1433

Port / May 20, 2017

In this very short video, I walk you through the step by step process of opening the 1433 firewall port for SQL Server. I am doing it because I am setting up a new System Center Operations manager server but the procedures would be the same for any other application that uses SQL Server for the database backend. Full Details on opening ports for SCOM can be found at
