HTTP:/1.1 500 Internal Server Error
If you are running two versions of ASP.NET, you may get HTTP:/1.1 500 Internal Server Error when creating a new Web project or opening an existing Web project in Visual Studio.
This problem may occur when IIS is not sure what version of ASP.NET to use or where to locate ASP.NET files. One of the following solutions should fix the problem.
Solution 1.
- Remove web.config file from inetpub/wwwroot directory
- Go to IIS, Right click on Default web site / All tasks / Check server extensions and let it run
- Reset IIS by right click on IIS or call iisreset from Run command
Solution 2.
- Install ASP.NET again using the following command from your Run command: C:\WINNT\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe –I
Make sure to change the windows folder and ASP.NET version folder with the version what you want to install - Reset IIS
Solution 3. Applies to Windows Server 2003
Note: This is a Microsoft KB article:
When you try to create a new Microsoft ASP.NET 1.1 application after you change the script mapping of the existing ASP.NET 1.1 Web application to ASP.NET 1.0 on a Microsoft Windows Server 2003-based computer, you may receive the following error message:
The Web server reported the following error when attempting to create or open the Web project located at the following URL: 'http://localhost/822319ev1'. 'HTTP/1.1 500 Internal Server Error'.
CAUSE
This issue occurs because Windows Server 2003 does not allow two versions of ASP.NET to run in the same application pool.
WORKAROUND
To work around the problem, do one of the following:
Restart the IIS before you create a new ASP.NET 1.1 application. At the command prompt, type the following command: iisreset
OR -
Create an ASP.NET application in a separate application pool. Create the script-mapped application (ASP.NET 1.0) in a separate application pool -- for example, in the ScriptMapappPool application pool. Then, create a new ASP.NET 1.1 application in an application pool other than ScriptMapappPool. For more information about how to create an application pool, visit the following Microsoft Web site: Configuring Application Pools http://msdn2.microsoft.com/en-us/library/1kdfe21k(VS.80).aspx

I need to be able to do an Amazon lookup based on ISBN for several books which are listed in a local database. I need the book info and seller information. I'm not sure which Amazon product I should be using. Where would I find sample code? ColdFusion is preferred, but Asp.Net Using C# is a good alternative. I've looked through several of the documents, but don't find an answer. A lot of the documentation listed is before the signed request change, and it seems there have been recent changes that are not in the samples or help files. When I signed up for Amazon support, they said they don't support the Advertising API. I'm not sure I should be using the Advertising API. Please HELP Me ! Norm, [email protected]

Hi, I am running Microsoft Visual Studio .NET 2003 in my new laptop with Windows XP professional. After the fist installation the Visual Studio .NET 2003 was working fine and I can open a new Web Application with no error. But now if I am going to open a new or existing Web Application the error will show this message "HTTP:/1.1 500 Internal Server Error". I don't really know what I have done to make it happen and If I will open other project like new Windows Application it works fine except for Web Application. I tried to open my existing Web Application from other computers and it works fine also but in my laptop it has an error.
