hyper-v 虛擬主機 匯出至網路芳鄰 產生錯誤 0x80070005

hyper-v 匯出到某一台有開分享資料夾的電腦時，會產生  0x80070005 的錯誤。
但已確認過在操作匯出的這個 server登入帳號是有權限在分享資料夾裡寫入檔案的權限。
原來是因為在匯出hyper-v的虛擬主機至其他電腦的分享資料夾時，分享資料夾的權限不能只開給操作者的帳號，還要開寫入權限給hyper-v的那台實體主機。
如果
A使用者  把 aa實體主機上的 bb虛擬主機 要匯到 cc主機上的分享資料夾，
在  cc主機上的分享資料夾 要開寫入權限給  A使用者帳號 & aa實體主機帳號 才會成功。

可參考下面的說明
