I have tried using SQL Server authenticated Database it worked but with this Windows authenticated DB, I can't figure out what to do.
What could be the problem?

[WebMethod]

public static List<string> GetEmployeeName(string empName)

{

    List<string> Models = new List<string>();         

    using (SqlConnection con = new SqlConnection(@"Data Source=PHAPPCVTSQL04; Initial Catalog=ECP_IQCDATA_SEM; Integrated Security=True;"))

    {

        using (SqlCommand cmd = new SqlCommand())

        {

            cmd.CommandText = "SELECT DISTINCT [Model] FROM [MRB_Model-Approver]";

            con.Open();

            cmd.Parameters.AddWithValue("@SearchModel", empName);

            SqlDataReader dr = cmd.ExecuteReader();

            while (dr.Read())

            {

                Models.Add(dr["Model"].ToString());

            }

            con.Close();

            return Models;

        }

    }

}  

try it

SqlConnection(@Server=PHAPPCVTSQL04;Database=myDataBase;Trusted_Connection=True);

Or

SqlConnection(@Server=.;Database=myDataBase;Trusted_Connection=True);
