Hi Thom again, at the moment I cannot afford to do much, but crucial is that I copy all my data and make sure of copies of all my applications, etc (this I can do now); in the mean time, it's crucial (I'm a self-employed graphic designer where the internet connection is vital to my survival) in case the HD blows, to port over everything necessary to continue my dialup and broadband internet connections, to another identical machine (a friend's who is not yet internet connected, living in the same house and happy to help in case of a crisis). Can you or anyone else please inform me of what files exactly I need to copy to the other machine in order to set up the identical internet system? Stuff like the TCP/IP control panel, Remote Access control panel, etc. thanks again michaelP > Michael, > > It sure is something to be concerned about.
