Now exit regedit and you should be able to browse to \\vmware-host and map drives to the shared folders underneath. You will have to remap all your previous drives. They wont come back automatically.
You can also create a simple bash script that looks like this, name it brokenvmnetworking.sh, and run it with ./brokenvmnetworking.sh from the terminal if you don't feel like copy/pasting it.
#!/bin/bash
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --stop
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --start
