I have configured SQL Server engine to listen on port 6893, an arbitrary port, using SQL Server Configuration Management tool. And I have also enabled TCP/IP protocol.
I have don this process more than a hundred times on many servers, but this time for unknown reasons I can't connect to the engine, outside SSMS.
The point is, SSMS gets connected using .,6893 address. But when I telnet 6893 I see that the port is not open, and even I can't connect using a connection.udl file.
I also turned off the Windows firewall completely. And I'm working just inside the server Windows, remotely.
What should I do?
