Linked table ms access 2010 change connection string

Question

I am working on a existing MS Access 2010 project that has a linked table link to Sql Server database.

When I mouse over to the linked table I can see a connection string 'ODBC;DRIVER=SQL Server;SERVER=10.0.0.1;UID=testdb;APP=Microsoft Office 2003;WSID=abc;TABLE=dbo.user'

This looks like a dsn-less linked table.

Question

1. Where the connect string locate at? How to change it (example database name)?

2. How can I create a similar dsn-less linked table? Anytime when I create a linked table Access 2010 always force me to choosecreate a dsn (file or machine).

To print all connection strings:

Dim tdf As TableDef
Dim db As Database

    Set db = CurrentDb

    For Each tdf In CurrentDb.TableDefs
        If tdf.Connect <> vbNullString Then
           Debug.Print tdf.Name; " -- "; tdf.SourceTableName; " -- "; tdf.Connect
        End If
    Next

To create a linked table:

With CurrentDb
    ''If the table does not have a unique index, you will need to create one
    ''if you wish to update.
    Set tdf = .CreateTableDef("LocalName")
    tdf.Connect = "ODBC;DRIVER=SQL Server;SERVER=10.0.0.1;" _
      & "UID=testdb;APP=Microsoft Office 2003;WSID=abc;TABLE=dbo.user"
    tdf.SourceTableName = "TABLE_NAME"
    .TableDefs.Append tdf
    .TableDefs.Refresh
End With

To change a link:

    Set db = CurrentDB
    Set tdf = db.TableDefs("MyTable")
    tdf.Connect = "ODBC;DRIVER=SQL Server;SERVER=10.0.0.1;" _
      & "UID=testdb;APP=Microsoft Office 2003;WSID=abc;TABLE=dbo.user"
    tdf.RefreshLink
