Hi, yes i am also facing the same problem.
It can't even work on a fresh Windows 7 installation. And even just updated to the latest firmware 1.54 (Build 15).
I know the Java works, and the activeX works on XP w IE8.
It was working when the drac was first installed serveral months ago, but only gave this problem in the last 1 month.
Is Dell working on a fix??
