When I remote desktop into a server, I get a loud beep coming out of my local machine whenever certain messageboxes pop up.
(An example is to search for something in the Event Log - when the search finds no results, I get a message box accompanied by a loud beep)
Annoyingly, the beep still happens even if I have sound turned off locally or the volume right down - it seems to be hooking in to some low level OS-beep mechanism.
Any way to turn it off?
Try disabling the internal PC speaker driver, beep.sys.
Slightly more subtle, you can disable it at the registry level:
