I have a Qnap 219P NAS, one MacBook Pro, one Windows XP machine and one Windows 7 machine connected to the same network.
I've enabled both AFP and SMB networks services on the NAS.
Connecting to the NAS from my MacBook Pro or Windows XP machine works fine but I can't connect to it from the Windows 7 machine.
I get successful replies when executing
ping <nas-local-ip>, but I can't reach the NAS's web administration page nor the Samba share. It seems like the NAS is totally hidden for Windows 7 but no other computer within the network.
I've tried other Windows 7 machines with the same result.
Does anyone have any ideas?
