Windows Server 2003 IIS呈现ASP.NET 4.0页为空白

Question

I have a web project which works fine on my local development machine.

I copied the project to our UAT server, setup a virtual directory pointing to the project and configured it to run on .NET Framework 4.0. I even added the Default.aspx page to the Documents tab. I configured Directory Security to use Windows Authentication.

When i try to access any web page within this application, IIS responds with a blank page. I looked through the event logs and don't see any errors anywhere.

Can someone please help me understand what's going on and how to remedy this?

Thanks in advance!

If you're just seeing a white page with no errors in the event log, it sounds like it could be a problem with the application rather than the hosting environment.

However, there are a few things you could try to doing to troubleshoot this.

• Check folder permissions. Try allowing "Everyone" access on your webroot folder and see if that makes any difference.

• Confirm that the IIS path is set up correctly but putting a text file in your webroot folder, and then browsing to it and verifying that it's contents are displayed.

• Create a basic test.aspx page without any script, just a "Hello World" bit of text, and try browsing to it. Confirm that it displays the correct content.

• Edit web.config and turn off custom errors

• Try re-registering the ASP.NET extensions with IIS using aspnet_iis ( details here )

Hopefully, one of these tests will be able to give you some kind of detailed error message or more insight into the cause of the problem.

For IIS 6.0 on Windows Server 2003, after the install of .NET Framework 4.0, the process of creating Web Sites or Virtual Directories that run under .NET Framework 4.0 is as follows:

1. Create a new application pool. Applications running under different frameworks can't be hosted in the same application pool, ie create an application pool perf framework.

2. Next, if you are creating a local intranet site or virtual directory, ensure that you don't have "dots" in the application name. Browsers confuse the dots to be external web sites, forcing them to run under internet zone as appose to the intranet zone.

3. Once you create your web site or virtual directory, make sure that it runs under an application pool dedicated for .NET 4.0 applications.

4. Ensure that when creating your website or virtual directory, you click on the ASP.NET tab and select version 4.0 from the drop down.

5. Then you may configure as per normal, with any other additional settings you may require.

Hope this helps someone experiencing similar issues. Took a while to figure out.
