I'm starting a new gig on Monday. Gonna be the Art Director at a very small marketing firm. Anyway, the current setup is 2 iMacs and 3 all-in-one HP machines. Everything is new within the past 2 years. The problem is that they don't have any sort of file server. All files are saved locally on every computer. Occasionally, they use DropBox to share files that are too large to email to each other. Ugh. I was thinking of suggesting a Mac Mini server and a Time Machine for backup. Apple's propaganda seems to indicate that it can exist peacefully on a mixed OS X / Windows network. But does anyone have any actual real-world experience with this sort of setup? I'm looking for a solution that will make file sharing in the office a bit easier and require very little maintenance, as I don't really want to spend much of my time being an IT person. Thanks.
