如果你用ODBC connection (DSN or DSN-less)來訪問遠端的(UNC path)數據庫, OLEDB會出現以下錯誤信息：

Microsoft OLE DB PRovider for ODBC Drivers error '80004005'

[Microsoft][ODBC Microsoft access Driver] The Microsoft Jet database engine cannot open the file '(unknown)'. It is already opened exclusively by another user, or you need permission to view its data.

      你完全可以避免這種錯誤--asp和ActiveX支持兩種方式打開MDB文件的DSN-less連接，或由其它機器訪問MDB文件。

      1. DAO database (only for small load)

  Dim File, Conn, RS
  Const ReadOnly = False
  File = "//server/share/file.mdb"
  Set Conn = CreateObject("DAO.DBEngine.35").Workspaces(0).OpenDatabase(File,,ReadOnly)
  Set RS = Conn.OpenRecordset(SQL)

        2. ADO + Jet OLE DB provider

  Dim Conn, RS
  Set Conn = CreateObject("ADODB.Connection")
  Conn.Provider = "Microsoft.Jet.OLEDB.4.0"
  Conn.Open "//server/share/file.mdb"
  Set RS = Conn.Execute(SQL)


你得確定使用ASP的用戶有NT的數據庫及共享訪問權限。
      假定有權限的話，你亦可訪問其它機器中的開放數據連接:

    'http://www.pstruh.cz
    Set UM = CreateObject("UserManager.Server")
    UM.LogonUser "Login with the rights", "PassWord", "Domain"
...
open database
...
    UM.RevertToSelf
