"The network address is invalid" for SQL Cluster Resource Name

Error Message:

The given network name is unusable because there was a failure trying to determine if the network name is valid for use by the clustered SQL instance due to the following error: 'The network address is invalid.'

Found the solution: 

there is nothing wrong with my AD/DNS setup. And after uninstalling the VirtualBox Guess Tool, it works.
