J ai recemment rencontre des pb avec ce logiciel (je ne sais pas si ce sont exactement l memes que ceux eviques dans le post initial). Comme j ai reussi ales resoudre, j avais prepare un post en anglais en vue plublication sur sites anglophones. J ai la flemme de le traduire, mais s il peut servir a quelqu un, le voici:
If it can be of some help, here is my experience about Apple Remote Desktop (3.5) problems, and the workaround I have found to solve them.
I have four Macs at home (3 iMacs + a MacBook). I have now installed Apple Remote Desktop on the main machine, the others acting as satellite machines, which I can observe and control in distant mode (which is why I bought this application).
Before and after installing Lion (on the four machines), I experienced some somewhat random problems with Apple Remote Desktop being unable to access to the satellite machines, whereas these where recognized as present in my private network (= visible by Bonjour Browser, as well as accessible through standard Finder system ( Go -à Network)).
I have resolved this as follows : on each satellite machine, in System -à Preferences -à Sharing options, activate screen sharing (instead of remote control, which is the option you normally activate if you are Remote Desktop User, otherwise you do not get anything more with Apple Remote Desktop than what you already have in standard system functionality). NB : For some strange reason I cannot understand, these two options (Screen sharing versus remote Control are exclusive).
Then, on the main computer, (outside Apple Remote Desktop), access to the Screen sharing functionality through the standard system Finder functionality (go -à Network -à machine selection + Screen Sharing click).
This normally works (possibly after you enter the username & password through which you want to access to the distant machine, username which of course has to match what you have specified within the system à share options of the distant machine). The, coming back to The sharing options on the satellite machine, and reversing from Screen sharing to remote control, Apple Remote Desktop miraculously works again on the main machine.

It is also important to note that in case each machine of your network uses a different user name and an associated password, you have to be aware of indicating the specific user name & password applicable to the satellite machine you want to access to. I had problem with AppleTV which I could resolve this way : the AppleTV password is unique, therefore if you have different password on your machines, it cannot work for all. I have suspected for a long time Firewall problems (either the standard Apple one, or the Intego one I have also installed), but I finally concluded that my AppleTV problems were not related to a Firewall problem, but to this password issue.
