• reconfirm all configuration steps
• confirmed the URL you are entering (test using the ip address as well as the localhost URL and double-check the port number used)
• confirm IIS is running
• confirm IIS is using .NET 2
• confirm the AyaNovaWBI app is using .NET 2

If you continue to experience an issue, perform the suggestions below, testing again after each.

1. Check that ASP.NET is enabled (for example Windows 2003 Server's IIS is not enabled by default).

• In IIS Manager, expand the local computer, and then click Web Service Extensions.
• In the details pane, click ASP.NET, and then click Allow.
• You can also check this by Computer Management as per the screenshot below

2. Repair the Microsoft.NET Framework 2 installation

• Open Control Panel -> Add/Remove Programs
• Select Microsoft.NET Framework 2 and select Change/Remove
• Select Repair
• This will take at least 5 or more minutes
• When finished, you must reboot the computer
• Once loaded back up, confirm IIS is running, confirm IIS's Default Web Site is using .NET 2, and the AyaNovaWBI app is using .NET 2, enter in the URL and the login page for WBI will now come up

3. Repair the links between .NET 2 and IIS - as per the Microsoft topic http://support.microsoft.com/default.aspx?scid=kb%3ben-us%3bQ306005

To fix IIS mappings for ASP.NET, run the Aspnet_regiis.exe utility:

• Click Start, and then click Run. 
• In the Open text box, type cmd, and then press ENTER.  
• At the command prompt, type the following, and then press ENTER:
  "%windir%\Microsoft.NET\Framework\version\aspnet_regiis.exe" -i

In this path, %winver% is the Windows directory for your operating system, and version represents the version number of the .NET Framework that you installed on your server. You must replace this placeholder with the actual version number when you type the command. 

Refer to the Microsoft topics http://support.microsoft.com/default.aspx?scid=kb%3ben-us%3bQ306005 and http://msdn2.microsoft.com/en-us/library/k6h9cz8h(vs.80).aspx for additional information on using aspnet_regiis.exe
