Windows自帶pptp的VPN連線方式，不用安裝任何軟體就可以使用VPN連線，但是從8.1開始，居然把斷線自動重撥的功能拿掉了...
還好有變通方法可以使用...不過有點麻煩...就是使用工作排程器，偵測斷線的事件20226 & 重撥失敗的事件20227
1. 使用工作排程器，新增一個工作
2. 觸發程序 選擇 當事件發生時
3. 紀錄檔 選擇 應用程式
4. 來源 RasClient
5. 識別碼 20226
6. 再新增一個觸發程序 識別碼 20227
7. 動作 新增一個 啟動程式 指令碼填 rasdial
8. 引數填 "VPN_NAME" id pw
9. 完成
這樣就能夠自動斷線重連了(手動斷線不會)
嫌麻煩也可以利用以下的XML檔匯入...VPN_NAME記得修改
