Dell and many other vendors take forever to support modern browser technologies. They really need to keep up. Also, browser vendors have to pick up the slack for these slackers sometimes also.
When navigating to Dell DRAC or any other website that runs off of Java. You may run into a .jnlp error where you can't launch the file. This Java drop download and launch option doesn't work for Dell DRAC (But it does work for KVM's).
Here you go.
1. Log into Dell DRAC and click on launch:
2. Go to your downloads folder and change the extension at the end of the file. (Just click on it and at the end of the file type .jnlp and hit enter) This will make the file a JNLP file.
3. Double-click the filename and launch:
Yes. It's a pain in the neck workaround, but until Dell test's it or Google fixes launching Java files. This is what will work.
