I have a Windows XP Network at home and just bought my first Mac. I plan with time to switch most if not all of the computers to Mac. I store a lot of my data on the main computer so frequently have to access these files. On Windows XP I map these drives but I can't find out how to do this on OS X. I know I can find the network and log onto these folders but as soon as I restart the computer they are gone. Is there any way to keep this from happening?
