    Here is the error: A connection was successfully established with the server, but then an error occurred during the login process, error 0, No process is on the other end of the pipe. What cause this error and how do I fix it?

    SQL Server 2016

    Visual Studio 2017

    Here is my connection string:

    string connectionString = @"Data Source=BRENTHUMBER\BRENT;Initial Catalog=BrentPractice;Integrated Security=False";
                SqlConnection conn = new SqlConnection(connectionString);
                SqlCommand cmd = new SqlCommand();
                    string strCommand = "Insert INTO Tracker(id, edi, personsName, date, descriptor, details, reasons, notes)";
                    cmd.CommandType = CommandType.Text;
                    cmd.CommandText = strCommand;
                    cmd.Connection = conn;
                    conn.Open(); // <-----------------------------------------error here

    string connectionString = @"Data Source=BRENTHUMBER\BRENT;Initial Catalog=BrentPractice;Integrated Security=False";

    You have to specify DB user Id & pwd in connection string.

    Integrated Security=False"

    If false, then you have to put user-id and password in connectionstring to logon to the SQL Server database.

    Hi bthJ6,

    Just like what budugu and DA924 said, when we set Integrated Security=False:

    Comes from msdn document:

    When false, User ID and Password are specified in the connection. When true, the current Windows account credentials are used for authentication.

    Recognized values are true, false, yes, no, and sspi (strongly recommended), which is equivalent to true.

    So, in the connection String, you should add user id and password(which can login this database) in it.

    The connect string should be:

    string connectionString = @"Data Source=BRENTHUMBER\BRENT;Initial Catalog=BrentPractice;Integrated Security=False;User Id==XXXX;Password=XXX";

    Best Regards,
