Issue/Introduction

Problem: 

Trying to rediscover routers through the RA web gui gives the following error:

The request failed with http status 404: Not Found

This only impacts RA 9.0.

 

Resolution:

This is caused by .NET 2.0 not being allowed in the IIS configuration. To resolve, follow these steps:

RDP to each Harvester server, or the RA standalone server.

• Right-click on My Computer and select Manage
  
  
• Go to Internet Information Services (IIS)
  
  
• Expand web service extensions
  
  
• Select ASP.NET v2.0, ASP.NET v1.1, and Active Server Pages and then hit Allow
  
  

  <Please see attached file for image>

  
  
  
• Open a command prompt on the server
  
  
• Run the following two commands:
  
  C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -r
  
  iisreset

Then refresh the enable interfaces page and try it again.

Note: For Win 2008, IIS v7 the 'Web Service Extensions' are located under IIS Manager >Server Name then in the icons on the right click on 'ISAPI and CGI Restrictions'

 

Additional Information: 

Please note that RA 9.0 is end of life and you should consider upgrading to ensure that you are running a supported environment.
