Website non responsive

Clarifications

You could try opening the command prompt and enter the command ipconfig /flushdns to see if that helps

Both IE and FF support add-ons. Try accessing the web site with all add-ons disabled. Run it in default mode, using all standard defaults for system values. Another problem is that configuration might have been tweaked.

Proxy server settings, and particularly net mask for proxy server? They're a little more obscure, and if things work OK on the intranet, but not on internet, it might be a possibility. You might also try TRACERT and see if the route is the same for both the good and bad machines.

If that doesn't work, check network settings for the affected machine, both on the machine itself and in any servers/routers/bridges/gateways along the way.

And finally if all else fails, try reinstalling windows on the affected machine.

This issue might occur due to some "add-ons" of any application running in background. Try the below steps and this should resolve the issue that you are encountering -

1. Close all applications
2. Close / disable startup applications (such as Skype, messenger, or any background applications)
3. Start > Settings > Control Panel > Internet Options > Delete Browsing History > Delete All (in passwords)
4. Also delete files and settings stored by add-ons (check) and click ok
5. Close all windows, and files, (just in case). Nothing has to be open
6. Go to Start > Run
7. Type %temp% in the field
8. Press Enter
9. Start deleting the temp files
10. You might not be able to delete some of the files, because they might be in use. Leave them alone.
11. When you get the error "Error - Deleting file or folder", click OK and continue deleting some of the files by type
12. When you are done. Reboot the computer

Now try to open the website that you were having trouble with
