問題：我正在查找每個WellKnownSidType枚舉成員的帳戶名稱和SID，如下所示。
爲什麼它有時會失敗？
爲什麼它在將WellKnownSidType轉換爲sid時有時會失敗？
據我瞭解，只有從sid到accountname的轉換有時會失敗，甚至只有當賬戶不是本地的而且不在域中的時候。
WellKnownSidType爲什麼有時無法轉換爲sid /帳戶？
例如，平移所述枚舉LogonIdsSid到SID的情況下，我得到：
Bekannte的SID DES Typs LogonIdsSidkönnennicht標準化。創建werden。
（類型LogonIdsSid的已知的SID不能創建。）
或查找的帳戶名的NTAuthoritySid
當我得到：芒奧德全部identitätsverweisekonnten nichtübersetztwerden。
（部分或全部idendity引用不能轉換。）

你的意思是什麼樣的失敗？你得到一個例外嗎？ – 2011-02-18 17:30:45
