  • You need to switch to mixed authentication mode. Follow below steps - 

    1. Right click on the server name and select Properties
    2. Select Security tab
    3. Enable the SQL Server and Windows Authentication Mode
    4. Restart the SQL Server service

    Apart from above also ensure that - 

    • Go to SQL Server Configuration Manager (SSCM)
    • Ensure Shared Memory protocol is enabled
    • Ensure Named Pipes protocol is enabled
    • Ensure TCP/IP is enabled

  • Is that a remote SQL Server? Then may a Firewall blocks the access, see Configure the Windows Firewall to Allow SQL Server Access

  • It is unlikely that it is a firewall issue, since connection was established. Even less so when it says "shared memory provider" - this indicates that you are connecting to an SQL Server instance on your local machine. Is that so?

    With no knowledge of  your envrionment it is difficult to understand what may be going. Assuming that this is an SQL Server instance on your lap/desktop, the first thing to try is to go the SQL Server Configuration Manager and restart the instance.

  • Hi Mat,


    Could you please check whether the SQL Server Browser is started. If not, please starting it.


    Could you please check the Maximum number of concurrent connections in Server Properties. To see whether the connection has reached to maximum. If it is possible, please set the value to 0(unlimited).




    In addition, I'll appreciate that you can provide us the error log for analysis.
