I'm running the latest version of Parallels (3.0 build 5160). Have created 2 WinXP VM's on one Mac and one on another. All are configured to use Bridged Ethernet and are assigned IP's by the DHCP server in my cable modem. I've confirmed the IP addresses are in the proper subnet. All VM's can ping both Macs. All VM's can ping my network printer as well. But none of the VM's can ping each other. This wasn't the case in earlier builds; my VM's used to be visible to each other. I've reinstalled Parallels Tools, rebooted, etc., to ne effect. Anyone have any ideas as to what's going on?
