Intel has a product - Intel Modular Server http://www.intel.com/content/www/us/en/modular-server/modular-server.html
This is kind of a blade server and it has Web Console for Management.
In this console you can use KVM for remote server management.
To run KVM session .jnlp file need to be downloaded.
Latest versions of Firefox fail to download .jnlp file. The last stable version which can download this file is Firefox 15.0.1 - https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/15.0.1/
In older versions something has changed and now it doesn't work.
Changing Java versions don't help.
can you provide the link of that jnlp file from where we can download?
