My HD had to be reformatted and needless to say the settings were lost. D'oh, indeed.

Sadly for us, the manual that I expect to have come with the v11 cd-roms are nowhere to be found. And looking for help online had brought me here.
Can anyone tell me how I can get Sage on my computer to talk to the other 2 computers on our little network? I know I need to set the data path to the correct computer, but how do I do that?
Is it absolutely necessary to have that ODBC? My manager's computer is apparently communicating fine without ODBC (I've been told this, but not seen his Control Panel myself) with the 3rd computer, which I have been told acts as the "server".
We're running v11, on Windows XP home edition with SP2.
Any help is much appreciated. If there's anymore hard/software info that I need to put up before you can help, please PM me. Thanks!!
