我的IIS出了问题,打开页面就是显示这种错误:

Server Application Error
The server has encountered an error while loading an application during the processing of your request. Please refer to the event log for more detail information. Please contact the server administrator for assistance.

在系統日誌顯示以下錯誤的話; 在计算机用户管理中删除启动iis及来宾账号,重装一次IIS即可

我照你说的做了,现在错误变成这样了

Faulting application dllhost.exe, version 5.1.2600.2180, faulting module ntdll.dll, version 5.1.2600.2180, fault address 0x00018fea.

這個錯誤沒見過
不過dllhost.exe是運行com+的進程
而且上面提示你系統調用自定義組件時,組件出現異常

可能是某個dll出錯了

我根本不知道什么自定义组件呀，
