今天自己的电脑上发布一个asp.net到iis上时，出现了这个错误，baidu一下解决了，记录下来，以便以后在遇到时可以迅速解决。

开发工具：vs2010

windows：win7

iis：6（window 7 自带的）

发布后出现错误：

出现原因：由于先安装.NetFramework v4.0后安装iis6所致（百度的，不知道是否正确）

解决方法：以管理员的身份运行vs命令行工具，然后运行一下asp.net_regiis.exe -i 命令，安装成功后重启iis便可，如下图：

IIS 7.5 error: Handler “PageHandlerFactory-Integrated” has a bad module “ManagedPipelineHandler” in its module list

Today I installed Clean Windows Web Server 2008 R2 64-bit with IIS 7.5. To my surprise opening .NET 4.0 application I received the following error:


IIS 7.5 Detailed Error - 500.21 - Internal Server Error

Server Error in Application "DEFAULT WEB SITE"
Internet Information Services 7.5

[Error Summary]
HTTP Error 500.21 - Internal Server Error
Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module list

[Detailed Error Information]
Module IIS Web Core
Notification ExecuteRequestHandler
Handler PageHandlerFactory-Integrated
Error Code 0x8007000d
Requested URL http://localhost:80/default.aspx
Physical Path C:/inetpub/wwwroot/default.aspx
Logon Method Anonymous
Logon User Anonymous

[Most likely causes:]
•Managed handler is used; however, ASP.NET is not installed or is not installed completely.
•There is a typographical error in the configuration for the handler module list.

[Things you can try:]
•Install ASP.NET if you are using managed handler.
•Ensure that the handler module's name is specified correctly. Module names are case-sensitive and use the format modules="StaticFileModule, DefaultDocumentModule, DirectoryListingModule".

[Links and More Information]
IIS core does not recognize the module.

As it turns out, some glitch caused this problem, and somehow .NET was not registered with IIS.

Running the following commands solved this issue:

%windir%/Microsoft.NET/Framework/v4.0.30319/aspnet_regiis.exe -i
%windir%/Microsoft.NET/Framework64/v4.0.30319/aspnet_regiis.exe -i
