Initialize the SQL Server Browser Service.

try using IP instead of pc name. If the ip working, then it might be the name pipe is not enable. If it;s still not working then the login using windows might be disabled.

I had this problem. So I put like this: PC-NAME\SQLSERVER Since the SQLSERVER the instance name that was set at installation.

Authentication: Windows Authentication

Connects !!!

go to services and start the ones related to SQL

Solution 11:[11]

My issue occurs when I add a PC to a domain. Restarting the service, making sure it's running, that it has the correct credentials to run, etc, as in other answers doesn't work. I don't know exactly what the problem is, but I can't even log in with the local user anymore to give the domain user access. Here's the steps that work for me:

In SSMS

  • View > Registered Servers
  • Database Engine > Local Server Groups > right-click pcname\sqlexpress
  • Delete > Yes
  • Right-click Local Server Groups > Tasks > Register Local Servers
  • It confirms that it re-registered. pcname\sqlexpress reappears.

I'm then able to log in with the local windows auth'd user again, my databases are all there and everything. I then go about my business adding the domain user to Security > Logins.

In my case, I was copying and pasting the server name from appsettings.json as;

DESKTOP-IVQP9DJ\\SQLEXPRESS.

So the problem was that there were two slashes in the server name which was causing the issue for me. If you are using .net core and copying/pasting server name like me make sure to use only one slash as:

DESKTOP-IVQP9DJ\SQLEXPRESS

Solution 13:[13]

If you already did that Then just restart the service :

  1. start menu
  2. Microsoft SQL Server 20xx
  3. Sql Server 20xx Configuration Manager
  4. SQL Server Service (at left tree)
  5. SQL Server (SQLEXPRESS) (at right region)
  6. right click -> restart
