    Can anyone help me solve this problem?

  • Hi,

    Could you tell me what authentication you have used to connect to the server. It seems to be that you are using windows authentication to connect to the server and hence it is getting failed. If this is the case, try connecting with SQL Server authentication.

  • Thanks for your reply, Ashok. I was using SQL Server Authentication.

    Actually, I logged in as windows authentication and created new user with sql server auth.

    username and password.

    but, when I logged in as new user, I encoutered with this error.

  • Check server properties if it is in Windows authentication mode....

    If so, then change it to mixed-mode authentication.

  • I changed the Server properties to windows and sql server authentication mode. But this time I have got this error.

  • Well...login problem is resolved...now its problem from the server-side.

    Restart the sql server service once...(if its not production:-))

    Check if the protocols(tcp/ip,shared memory) are enabled.

    Hi,

    As mentioned check whether the Named Connections are Enabled or not in the Server. If not Enable it and restart the server. Hope this will fix you problem.

    Also have a look at this,

    I have checked the authentication mode is mixed and still giveing me error.

    Any other solution there?

  • Hi Namish,

    Are you sure that your SQL Server has a user called "'rutikas"?

    Does your SQL Server allows Windows Authentication?

    Are you able to connect to your server thru SSMS using windows/sql server authentication [other than "'rutikas"]?

    Regards,

    Ashok S

  • No I could not login using this user at all. yes there is user called rutikas.

    I have got sql server and windows authentication mode enabled.

  • Hi,

    Really hard to identify your problem yaar. I'm sorry, I guess I can't help you :ermm:.

    Regards,

    Ashok S
