if i am not mistaken, Remote Assistance was included in NetMeeting,
before WindowsXP came into existence. therefore, you could still use
Remote Assistance by running NetMeeting, without having WindowsXP.
within the context you are asking about though, you could not use Remote
Assistance to install software on a remote PC, if the software you want
to install is not on or accessible to the remote PC (e.g. if the
software is in your hands). using Remote Assistance, you could install
the software on the remote PC, only if the software you want to install
is accessible to the remote PC.
now regarding Remote Desktop Connection (RDC).
using Remote Desktop Connection, you could install your software on the
remote PC, regardless of where it is (e.g. your local PC or the remote
PC), because your local disk drives can be accessed by the remote PC, as
well as vice-versa. the remote PC must have Windows XP Pro in order to
provide the server functionality, as mentioned by another posting.
the local client PC (used to connect to the remote) needs to have the
client RDC software. the client RDC software is included in Windows XP
Pro and Home. for other versions of Windows, the client RDC software
can be easily installed, either from the XP installation CD or from any
other media that contains the proper installation executable.
that's the advantage of Remote Desktop Connection. with Remote
Assistance, you are just remotely watching over the shoulder or (with
permission) remotely controlling the remote mouse and remote keyboard.
