具体情况如下:

到事件查看器里查看應用程式事件,發現有兩個錯誤,具體如下:
1.
Failed to execute request because the App-Domain could not be created. Error: 0x80070005 存取被拒.
2.
Failed to initialize the AppDomain:/LM/W3SVC/1549957242/Root

看到就頭暈,還是先百度一下,結果發現有很多人有出現過這種情況,于是一個一個點開來看想找到原因.
最開始是看有提示頁面錯誤和我一樣的人的解決方法,來來去去就是一個方法給大家轉來轉去,說是安裝好第一次使用比較可能發生此錯誤,即沒有註冊好,要重新註冊,方法如下:
1.首先開啟「命令視窗」，並切換目錄到 %SystemRoot%\Microsoft.Net\Framework\(%SystemRoot% 視你 Windows 安裝目錄而定，一般是在 C:\Windows)
2.執行 "net stop w3svc" 終止 w3svc 服務
3.切換到下層目錄 v2.0.5.xxx
4.執行 "aspnet_regiis.exe -ua" 解除 .Net 安裝
5.重新安裝 .Net 到 IIS 中 "aspnet_regiis.exe -i"
6.重新啟動 w3svc "net start w3svc".
但是還沒有找到原因是甚麼,於是再找,後來找到一篇有補充的,說執行"aspnet_regiis.exe -ua",會卸載全部asp.net的版本,不管是在那個版本的目錄下面執行此命令(這裡提醒一下,如果想要多個版本同時存在,慎用).我的暫時就只要v.2.0的就可以了.
看了好几篇都一樣,還是想把問題解決先,然後在繼續找原因.於是按上面步驟操作一遍,當我滿懷希望地在瀏覽器上刷新畫面時,結果卻還是提示原來的錯誤.鬱悶...........................
只好繼續找.後來找到答案,果然是iis沒有配置好,權限問題.權限問題還一直沒有弄明白.一開始我懷疑是權限問題,把"ISUR_電腦名 " 和 "IWAM_電腦名"這兩個網絡帳號的權限設定為完全控制,但是還不行,就不知道是哪裡出問題了.後來那篇文章說先把"Everyone"的權限全開,如果可以訪問,就是權限問題了,我沒有把"Everyone"的權限全開,只是默認的只讀和執行,還真的能訪問了,驚喜,於是按上面的方法把 "aspnet" 和 "iis_wpg"兩個帳號的權限也開了,只用默認的只讀和執行,然後把"Everyone"刪掉,依然能訪問,然後我再將"ISUR_電腦名 " 和 "IWAM_電腦名"這兩個帳號的權限也設置成只讀和執行,也一樣可以訪問.反覆試了几次,最後保留了"ISUR_電腦名 "(我在匿名訪問時是使用此帳號來登陸的),"aspnet" 和 "iis_wpg"這三個帳號的只讀和執行權限,可以正常訪問.哈哈,問題解決
