Overview

When accessing the GFI Archiver web interface, you receive the following error:

HTTP 404 Not Found: The webpage cannot be found.

Diagnosis

The GFI Archiver files could not be found because the web site was not started.  

Solution

1. Open the Services Console (services.msc)
   
2. Check that the IIS Admin Service and its dependencies are started, restarting the service if necessary.
   
   
   
3. Verify that the website is started:
   1. Go to Start > Administrative Tools > Internet Information Services (IIS) Manager.
   2. Expand the machine node, and expand Sites.
   3. Right-click the website that hosts GFI Archiver, and select Manage Website > Restart.
      
      
      
4. Make sure the Application Pool is started:
   1. From Internet Information Services (IIS) Manager, expand the machine node and select Application Pools.
   2. Confirm GFI Archiver Application Pool (ArchiverPool) is started.
      
      
      
5. Verify the Application Pool is set to ASP.NET v4.0 and Network Service:
   1. Go to Internet Information Services (IIS) Manager > Application Pools
   2. Go to GFI Archiver Application Pool and select Advanced Settings.
   3. From the Advanced Settings window, go to General > .NET Framework Version and make sure it's using v4.0.
   4. From the Advanced Settings window, go to Process Model > Identity and check that it's using Network Service.
      
      
      
6. Confirm ASP.NET has been registered with IIS and pages are set to allow using the article Registering ASP NET with IIS Web Server.

Note: If issues continue after following these steps you will need to troubleshoot IIS itself by following the guide from Microsoft for troubleshooting an "HTTP 404 - File not found" error message on a server that is running IIS.

Testing

After performing the solution to confirm you have access to the web interface, navigate to the Archiver URL and you should see a page requesting sign in (seen below), or will automatically be logged in depending on configured options for sign in.
