To resolve this issue please check your connection string. If you need any further help with it then please check Connection Strings, which has the list of commonly used ones.

Please find below the commonly used Connection Strings:

1.    SQL Server 2012

a.      Standard Security

b.      Trusted Connection

    Server=myServerAddress;Database=myDataBase;Trusted_Connection=True;

 

c.       Connection to a SQL Server instance

The server/instance name syntax used in the server option is the same for all SQL Server connection strings.

    Server=myServerName\myInstanceName;Database=myDataBase;User Id=myUsername;Password=myPassword;

2.    SQL Server 2005
