Last time when i installed Win7, i configured it to block some netbios names in LAN with hosts file. Something like this: 192.168.0.10 computer_name 192.168.0.10 computer_IP where 192.168.0.10 some ip-address in network, where user need to login to access it. So, when user trying to access computer_name via \\computer_name, he will redirect to 192.168.0.10 rather then going to computer_name. In Windows 8.1 I can't do this trick. I tried to disable Windows Defender, flushed DNS, nbtstat -R. Nothing works. When I pinging computer_name, IP address returning 192.168.0.10, but when I accessing it via explorer (\\computer_name\d$), it opening computer partitions. In Win7, when I trying to access \\computer_name, its trying to open 192.168.0.10 one. Maybe its not the best solution to do this, but it works in Windows 7.
