G'day Sam,
were they all on the same internet connection? If so I think I'd be having a look at the router/modem and/or the Ethernet switch, these all being common components. Windows really shouldn't have a problem with this. BTW, unless you're on a really exceptional broadband link, that 100Mbps is only the local LAN speed...

You're only paranoid if you're wrong!
