KNX IP Devices not being found when using Parallels on a Mac?

Sometime when using Parallels on a Mac the network connection can lock up causing IP Interfaces and Routers to not show up in ETS.

To solve this right click on the Windows desktop icon and select configure. 

Then change the network connection to either Shared or Default. If doesn't work then change it back to the original setting and ETS should be able to see the devices again as the interface will have reset. It will take a few seconds for ETS to scan the network connection after each change.
