HTTP Error 404 3-Not Found in IIS 7 5

Question

I m using IIS 7 5 on Windows Server 2008 R2 x64 Enterprise Edition  In the project we have developed with ASP NET 4 0 we used WCF Service  But it doesn t run over domain when the software is running from local computer  Otherwise  I am getting the following error      HTTP Error 404 3-Not Found      The page you are requesting cannot be served because of the extension   configuration  If the page is script  add a handler  If the file should   be downloaded  add a MIME map

I was having trouble accessing wcf service hosted locally in IIS. Running aspnet_regiis.exe -i wasn't working.

However, I fortunately came across the following:

Rahul's blog

which informs that servicemodelreg also needs to be run:

Run Visual Studio 2008 Command Prompt as “Administrator”. Navigate to C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation. Run this command servicemodelreg –i.

In my case  along with Mekanik s suggestions  I was receiving this error in Windows Server 2012 and I had to tick  HTTP Activation  in  Add Role Services

In windows server 2012  even after installing asp net you might run into this issue   Check for  Http activation  feature  This feature is present under Web services as well   Make sure you add the above and everything should be awesome for you

You should install IIS sub components from  Control Panel -  Programs and Features -  Turn Windows features on or off  Internet Information Services has subsection World Wide Web Services   Application Development Features  There you must check ASP NET   NET Extensibility  ISAPI Extensions  ISAPI Filters will be selected automatically   Double check that specific versions are checked  Under Windows Server 2012 R2  these options are split into 4  amp  4 5   Run from cmd    windir  Microsoft NET Framework64 v4 0 30319 aspnet regiis exe -ir  Finally check in IIS manager  that your application uses application pool with  NET framework version v4 0   Also  look at this answer
