We can't access your system so don't know why you can't connect. Do what the message says and ensure the instance name is correct (the SQLEXPRESS bit), that it allows remote connections, and also check for firewall issues on the port being used. If you google the error message you'll probably find a checklist of things to check.

Make sure you have typed in correct server instance name.
You can also click the dropdown and click browse for more to see the list of available instances and select the appropriate one.

Add/Enable port 443 (public too) on Windows Firewall and see if resolves the problem or at least if the error message changes

Try setting up a connection in VS with the Server Explorer pane:
1) Open Server Explorer.
2) Right click "Data connections" and select "Add connection"
3) In the dialog that follows, select your DataSource, and database, specify the security info, and press the "Test connection" button.
4) When the connection works, press "OK"
5) Highlight your database in the Server Explorer pane, and look at the Properties pane. A working example of the connection string will be shown, which you can copy and paste into your app or config file.

If you can't establish a connection that way, then you need to look carefully at where your DB is, and what you need to provide in order to access it.

Solution 3

you need to start this two services in SQL SERVER CONFIGURATION MANAGER.
1. SQL Server(MSSQLSERVER)
2. SQL Server Browser

And one more thing you need to enable the Protocols for MSSQLSERVER

Shared Memory   Enabled
Named Pipes     Enabled
TCP/IP          Enabled
VIA             Disabled
