New setup NIS 21.3.0.12 (on new setup Windows 8.1 with all update installed) block local network with rule "Default Block LLMNR".
If rule "Default Block LLMNR" is off, then rule "Default Block UPnP Discovery" block and etc.
I receive on computer the Network Error code 0x80070035 "The network path was not found".
This error only new setup, if update from an another version all works.
If firewall disable and then enable all work while restart os.
1 desk top PC is Windows 8.1 64 bit with NIS 21.3.0.12 - no network access.
2 desk top PC Windows 7 64 bit with NIS 21.2.0.38 - network access.
