I am receiving this message, "Parallels Desktop is unable to attach to the network adapter unknown. If this is the first time you see this message, please reboot your computer and start your virtual machine again. Otherwise please check your virtual machine's configuration and select another network adapter, or you will not be able to work with network connections inside your virtual machine." Any advice?
Hard to say without knowing your VM, configuration. The easy solution is to reinstall Parallels Desktop as described in http://kb.parallels.com/en/4790
