MBP w/Snow Leopard was upgraded from Parallels 6 to Parallels 7 (now at 7.0.15104), after which the shared networking stopped working in a (very old) XP VM. Reinstalled Parallels Tools, found no issues. Ping checks showed that networking was actually up, but could not resolve hostnames. Changed VM's TCP/IP-settings to Google's DNS address and everything started working. Cannot find any issues in the guest VM, and all DNS requests directed to the Parallels shared network gateway fail. Fired up a Windows 7 guest machine and it has the same problem. Anyone else see this?
