Login to local db with ip I install sqlserver and login with SSMS with windows auth. and server = DESKTOP-XXXXX\MSSQLSERVER01
When I tried to connect with 127.0.0.1 ot 127.0.0.1:1433 I can't
I put into TCP/IP
 but still I can't login with 127.0.0.1\MSSQLSERVER01
why is that?
If you installed a SQL server named instance, by defaut, it have to be contacted on a random port not ont the port 1433.
Please use 127.0.0.1\MSSQLSERVER01 or change the tcp/ip configuration and set a fixed port.
Verify that sql server agent is running. This is how a named instance is translated to the right dynamic or static port.
