Limit response size in WCF networks

I host the WCF service in IIS using basicHttpBinding. WCF Web Services query SQL Server 2008 using ADO.Net and return a DataTable to the client side of the WCF service.

I find that when the returned DataTable is large, there will be an exception, the specified http connection is closed by IIS. Any ideas what is wrong and how to set a larger response size? Another idea is if there is any hard limit on the serialization size of an object (I thought maybe the DataTable instance is too large for serialization?)

Error Information Returned by IIS:

Exception Message:

An error occurred while getting an HTTP Response at http: //labmachine1/service.svc . This can be associated with a service endpoint without binding the HTTP protocol. This could also be due to the HTTP context of the request being interrupted by the server (possibly due to the Shutdown service). See Server Logs for more information.

{"The connected connection was closed: An unexpected receive error occurred." }

Here is my entire source code for the server side, for the server on which I am located in web.config, there are no changes for the default values. Since I accept in IIS, I use basicHttpBinding.

public class StudentManagement : IStudentManagement
{
    public DataTable Poll(int Id)
    {
        return MakeParentTable();
    }

    private DataTable MakeParentTable()
    {
        // Create a new DataTable.
        System.Data.DataTable table = new DataTable("ParentTable");
        // Declare variables for DataColumn and DataRow objects.
        DataColumn column;
        DataRow row;

        // Create new DataColumn, set DataType, 
        // ColumnName and add to DataTable.    
        column = new DataColumn();
        column.DataType = System.Type.GetType("System.Int32");
        column.ColumnName = "id";
        column.ReadOnly = true;
        column.Unique = true;
        // Add the Column to the DataColumnCollection.
        table.Columns.Add(column);

        // Create second column.
        column = new DataColumn();
        column.DataType = System.Type.GetType("System.String");
        column.ColumnName = "ParentItem";
        column.AutoIncrement = false;
        column.Caption = "ParentItem";
        column.ReadOnly = false;
        column.Unique = false;
        // Add the column to the table.
        table.Columns.Add(column);

        // Make the ID column the primary key column.
        DataColumn[] PrimaryKeyColumns = new DataColumn[1];
        PrimaryKeyColumns[0] = table.Columns["id"];
        table.PrimaryKey = PrimaryKeyColumns;

        // Create three new DataRow objects and add 
        // them to the DataTable
        for (int i = 0; i <= 1000000; i++)
        {
            row = table.NewRow();
            row["id"] = i;
            row["ParentItem"] = "ParentItem " + i;
            table.Rows.Add(row);
        }

        return table;
    }
}

Client Code:

static void Main(string[] args)
{
    StudentIdentifier identifier = new StudentIdentifier();
    identifier.Id = 100;
    StudentManagementClient client = new StudentManagementClient();

    DataTable student = client.Poll(identifier);

    Console.WriteLine(student.Rows.Count);
}
