How do I fix 404.17 error on Win Server 2k8 and IIS7

Question

I've setup a new .net 2.0 website on IIS 7 under Win Server 2k8 and when browsing to a page it gives me a 404.17 error, claiming that the file (default.aspx in this case) appears to be a script but is being handled by the static file handler. It SOUNDS like the module mappings for ASP.Net got messed up, but they look fine in the configurations. Does anyone have a suggestion for correcting this error?

Answer 1

I had this problem on IIS6 one time when somehow the ASP.NET ISAPI stuff was broke.

Running

%windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i 

to recreate the settings took care of it.

Answer 2

This solution worked for me... (I've had aspnet_regiis.exe -i do some damage)

4.Restart the App Pool 

Answer 3

For me it worked by doing the following

Install ASP.NET

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

• Next Go to IIS Manager and click on the server (root) node.
• In features view, IIS section, open "ISAPI & CGI Restrictions"
• Right-click the ASP.NET 4 restriction column and right-click to Allow

Hope it works for you..
