Hi Guy's so where i am with this now, i am waiting for our IT company to assist onsite, until then i need to do the following but can't quite get this going properly
Certain Tables Delete
Certain Table Import
Certain Tables Convert To Local
This what i have so far but !!! your expert advice would be better 
Code:
DoCmd.DeleteObject acTable, "tblInvoices1"
Dim srcFile As String, srcTbl As String, DestTbl As String, DestFile As String
srcTbl = "tblInvoices"
DestTbl = "tblInvoices1"
DestFile = "C:\Users\David\Desktop\Accounts DMT Ltd.accdb"
DoCmd.DeleteObject acTable, "tblInvoices1"
DoCmd.TransferDatabase acImport, "Microsoft Access", DestFile, acTable, srcTbl, DestTbl, False
DoCmd.SelectObject acTable, "tblInvoices1", True
DoCmd.RunCommand acCmdConvertLinkedTableToLocal
MsgBox ("Tables Are Now Replaced With Linked"), vbInformation + vbOKOnly, "DELETED SUCESSFULLY"
Is there a easy fix to this ? i may have the source or destination the wrong way round
Kindest
