HTTP Error 404 Not found

I am in no way a computer expert, but after some searching, here is something that may help you...(not sure whether you're using Internet Explorer or Firefox)



For Internet Explorer...

From Microsoft Support (click here for the article):
"When you attempt to visit a Web site on your local network (intranet), Internet Explorer displays a page with the following error message: Error - 404 Requested Information / is unavailable. Failed to connect to server name of the Web server. reason: hostname unknown".

"This problem occurs when you add a forward slash to the end of a Web address that is specified as an exception in the proxy server settings".

Follow the solution in the article.



For Firefox...

"Open Tools, Options then click Advanced then Network. Click on the Settings tab. Check to make sure No Proxy is checked. If it isn't, check it then ok out of the Options. Restart Firefox. All being well it will now connect. If it doesn't, try turning off the firewall, then try Firefox again".

Also from Windows Help and Support...(Click the Start button on your computer and click Help and Support, then type "Proxy" in the Search bar.)

Why can't I view some websites?

If you can access some websites but not all of them, here are some possible causes:

• Your browser could be attempting to connect through a proxy server. If so, try connecting with the proxy server turned off.
  
• Your browser connection settings could be incorrect. To change connection settings, follow these steps:
  
  1. Click to open Internet Options.
  
  2. Click the Connections tab.
  
• Your router could be attempting to proxy DNS requests and failing. Refer to the documentation that came with your router for instructions on disabling DNS proxying.
  
• Parental Controls, Family Safety, or some other parental control software could be blocking access to certain websites.

Also, maybe try restoring to the default settings of your web-browser and disabling any plug-ins (except flash player). And check your firewall.
