That's it - the W10 will drop network connectivity after I switch to Mac and then back to VM. If I reboot the entire Mac the cycle starts again. I tried uninstalling and reinstalling Parallels Tools several times already. If I try to use "Troubleshoot" in W10 settings, sometimes it will say Invalid IP (or something like that). If I try to disable the Network Adapter, it will hang, or do nothing for a long period. TIA for assistance, this is driving me nuts!
