Jim, this didnt fix it. We worked it out though, we had to disable the beep in device manager/hidden devices, but only on the dell inspiron 9400's.

Then do a change user /execute from the command prompt. That has always fixed it for me.

Weird thing is however, its only bleeping for our users who have Dell Inspiron 9400 laptops !! anyone else had this, or got any ideas before I log a call with MS ? Thanks Andy
