Why do I have no TCP Port for my SQLEXPRESS?
I went to computer management-> SQL Server Network Configuration -> Protocols for SQLExpress -> TCP/IP but there is no TCP port. Is this normal? should I be assigning a number?.
Sounds like TCP/IP is disabled. It needs to be enabled in order to be assigned a port there. Configuration Manager > SQL Server Network Configuration > Protocols for SQLEXPRESS > TCP/IP < right-click, Enable, restart service.
^ When I enable this, I get a TCP/IP port; when it is disabled, it looks like your screenshot. Keep in mind you may not need to have TCP/IP enabled at all depending on how you are using the instance and you need to connect from.
Locally, you should be able to connect with 127.0.0.1\SQLEXPRESS - connecting from another machine might depend on other factors like firewalls and network routing. If you continue having issues even locally, you need to validate that:
- the SQL Server instance is running
- the SQL Server Browser service is running
- remote connections are enabled
- you are connecting with the right instance name
- TCP/IP is enabled
