    For me the issue was that the SQL server was in Windows Authentication mode only, even though I set it to mixed during the install.

    In the object explorer, right click on the server, properties and then the Security page and set Server authentication to SQL Server and Windows Authentication mode.

    i tried the troubleshooting steps in both microsoft tech articles, and oddly no luck.

    i managed to fix the solution by changing my authentication from SQL Server Auth to Windows Auth. Though I am not sure the technical reason why this works?

    FYI, I’ve just had the same error.

    I switched to Windows authentication, disconnected, then tried to login again with SQL authentication. This time I was told my password had expired. I changed the password and it all worked again.

    I got this error when I (deliberately) reduced the configuration of maximum SQL Server memory to 16Mb and restarted.

    So it might be a memory issue.

    It may help to make sure the database specified in the initial catalog exists.

    I encountered this problem when the password for the login that I was attempting to connect with had expired.

    1st check the Window’s Event Log for the following error:

    Could not connect because the maximum number of ’1′ user connections
    has already been reached. The system administrator can use
    sp_configure to increase the maximum value. The connection has been

    To solve the problem do the following:

    • Open Microsoft SQL Server Management Studio
    • Open a new query
    • Type the under given code and press the execute button

      sp_configure ‘show advanced options’, 1;
      sp_configure ‘user connections’, 0;


    In my case make sure that your connection string has ;password=
