http://localhost/ always gives 502 unknown host

Question

My service for World Wide Web Publishing Service started successfully but whenever I browse to http://localhost/ I always get 502 Unknown host. Also, wampapache is installed side by side but when I stop IIS service and start wampapache from services.msc I get error and when I view it in System event log I get this error:

- <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">

I am fed up of this error and it is driving me nuts. I feel like banging my head against the laptop. I am really serious. Without concentrating on my real application I am trying to solve this issue since 3 hours.

I google various threads and few of them said that there could be issue of Reporting Services or Skype. But I have uninstalled Skype and Reporting Services are disabled. What more should I do?

I have hosts file present in etc directory and it does have mapping for localhost to 127.0.0.1. What more could I do?

Answer 1

Check the ownership of your hosts file. It should be owned by SYSTEM.

Answer 2

Have you configured the binding in IIS manager?

Right click on your site, select 'Edit Binding', ensure as a minimal port 80 is added, host name and IP address (leave as default - All Unassigned) does not need to explicitly be defined if you are typing in localhost.

If you want to run side by side, change the port number or hostname.
