問題：
We have recently upgraded to IIS7 as a core web server and I need an overview in terms of the permissions. 我們最近升級到IIS7作爲核心Web服務器，我需要在權限方面進行概述。 Previously, when needing to write to the file system I would have give the AppPool user (Network Service) access to the directory or file. 以前，當需要寫入文件系統時，我會給AppPool用戶（網絡服務）訪問目錄或文件。
In IIS7 I see, as default, the AppPool user is set to ApplicationPoolIdentity . 在IIS7中，我看到，默認情況下，AppPool用戶設置爲ApplicationPoolIdentity 。 So when I check the task-manager, I see that a user account called 'WebSite.com' is running the IIS Process ('Website.com' being the name of the website in IIS) 因此，當我檢查任務管理器時，我看到一個名爲“WebSite.com”的用戶帳戶正在運行IIS進程（'Website.com'是IIS中網站的名稱）
However this user account doesn't exist if I try to use that to give permissions. 但是，如果我嘗試使用該帳戶授予權限，則此用戶帳戶不存在。 So, how do I determine which user to give the permissions too? 那麼，我如何確定哪個用戶也可以授予權限呢？

See below for the problem in screen shot. 有關屏幕截圖中的問題，請參閱下文。 Our website (www.silverchip.co.uk) runs on the username SilverChip.co.uk. 我們的網站（www.silverchip.co.uk）使用用戶名SilverChip.co.uk運行。 However when I add pemissions, this user doenst exist! 但是當我添加提交時，這個用戶確實存在！
