Re: Accessing Multiple ISPs on the fly

Beau:

Thanks, I'm trying to digest all the info you gave me. How do I dual
home the PCs (one is where the "My Documents" and Printers reside and the
other is the machine with the billing app) so they are always "related" to
the client machines?

ps:
The reasons I'm doing this are:
a) The LAN is set-up and running with a 32 port (+ one input) switch
connected through an ADSL router to one ISP. We recently contracted another
ADSL connection with a second (cheaper) ISP. We don't want to throw away the
present - good - switch to buy a new one.
b) We don't want to disconnect the previous ISP until (and if) the new
one proves to be better. Meanwhile we'll be testing both simultaneously,
allowing the user to change between them. If (big if) it might be worth our
while to have both ISPs together we would leave the setup permanently.
