Shared Networking wasn't working for me after upgrading from build 1970 to 3036. To solve it, follow these steps: 1. Shut down your VM. 2. Quit Parallels. 3. Go to Apple Menu/System Preferences/Networking 4. You should receive a message about "new network ports available". Click OK. 5. Reboot your mac. After this has been done, everything should work. Note: Parallels sometimes will tell you to do step 5, but it fails to tell you to do steps 3 and 4, which appear to be the key.
