This is probably a pretty noobish question, but here goes...
I've recently discovered Kyle Crawford's dockutil, but I can't make it work with Apple Remote Desktop. Or rather: I can't make it work with ARD's "Send UNIX Command" feature. It works fine on single machines (i.e. working in Terminal on a remote Mac controlled via ARD), but sending dockutil commands to multiple Macs (with dockutil installed on them) fails.
Why? And is there a solution?
If anyone can shed any light on this I'd be really grateful.
