We've created a 2 subnet lab on a Win2008 host using Vmware Server 2 and Freesco 0.3.8 . Our problem is that everything works fine for a while i.e can ping all servers in both subnets from all boxes, but then after a while i can't ping anything. if i reboot the Freesco it will fix it, though not everyt time. We then need to reboot all VMs. Any idea what would cause this?
