Try using code like this to do the linking.
I have used this method for over 6 years without any trouble.
I use this procedure to re-create links to SQL Server.
====================================================
For Jet re-linking code see:
http://www.mvps.org/access/tables/tbl0009.htm
====================================================
(This eliminates the need to re-name all the tables to strip out dbo_ and it
allows you to point to different versions of the same database easily.)
There is a local Access table (tblODBCTables) that contains the table names
and index keys I want to link to on the Server.
Note: the source table name needs the dbo. prefix which is in the code. The
linked table name usualy omits this. .
Public Sub LinkSQLServerTables(strDSN As String, strDatabase)
On Error GoTo Err_LinkSQLServerTables
Dim dbs As Database, rs As Recordset, tdfAccess As TableDef
Dim dbsODBC As Database, strConnect As String
If strDSN = "" Then
MsgBox "You must supply a DSN in order to link tables."
Exit Sub
Else
strConnect = "ODBC;DSN=" & strDSN & ";UID=User;PWD=password;DATABASE=" &
strDatabase & ";"
End If
SysCmd acSysCmdSetStatus, "Connecting to SQL Server..."
Call DeleteODBCTableNames
Set dbs = CurrentDb
Set rs = dbs.OpenRecordset("tblODBCTables")
Set dbsODBC = OpenDatabase("", False, False, strConnect)
Do While Not rs.EOF
Set tdfAccess = dbs.CreateTableDef(rs![LinkTablename], dbAttachSavePWD)
tdfAccess.Connect = dbsODBC.Connect
tdfAccess.SourceTableName = dbsODBC.TableDefs("dbo." &
rs![LinkTablename]).Name
dbs.TableDefs.Append tdfAccess
rs.MoveNext
Loop
rs.Close
Set rs = Nothing
Set dbsODBC = Nothing
Set dbs = Nothing
Exit_LinkSQLServerTables:
SysCmd acSysCmdClearStatus
Exit Sub
Err_LinkSQLServerTables:
MsgBox ("Error # " & Str(Err.Number) & " was generated by " & Err.Source
& Chr(13) & Err.Description)
Resume Exit_LinkSQLServerTables
End Sub
'This procedure deletes all linked ODBC table names in an mdb.

On Error GoTo Err_DeleteODBCTableNames
Dim dbs As Database, tdf As TableDef, I As Integer
Set dbs = CurrentDb
For I = dbs.TableDefs.Count - 1 To 0 Step -1
Set tdf = dbs.TableDefs(I)
If (tdf.Attributes And dbAttachedODBC) Then
dbs.TableDefs.Delete (tdf.Name)
End If
Next I
dbs.Close

This code is similar to the SQL Server code but shows how to use CREATE
INDEX and has some error handling.
You can copy this structure to the method aboce if you need to.

strSchemaPwd As Variant) As Boolean

QueryDef
Dim dbODBC As Database, strConnect As String, strSQL As String

MsgBox "You must supply a DSN in order to link tables."
Exit Sub
Else
strConnect = "ODBC;DSN=" & strDSN & ";UID=xyz" & ";PWD=abc;"
End If

'run pseudo index queries here. If the table does not exist then this
gets skipped.
