Server TCP provider failed to listen on [ ‘any’ 1433]. Tcp port is already in use.

Issue – Today I faced very weird issue; on multi instance SQL Server machine, couple of SQL Services was not starting after Server reboot ( In my case it was SQL 2014 and SQL 2016 ) and every time I was trying to restart my SQL Services, I was getting below error message –



Solutions – On error message it’s look like some other processes was trying to use SQL default port 1433.

Hence it was not allowing to restart SQL Services with Port 1433.

On my server, we have multiple SQL Services installed ( SQL 2008 to SQL vNext ) hence I started checking if any of these SQL Server have assigned static port 1433.

I start checking assigned port for all SQL Server and I found SQL Server 2014 and SQL Server 2016 was having assigned static port 1433.

In order to resolve the issue, I removed static port entry and restart my SQL Services and it started successfully.
