It could be a firewall thing. First, try disabling Windows Firewall or any other firewall software you may have running. If that works, then you can probably set up an exception in your firewall settings to open port 3306.
You should be able to run "telnet [ip_of_nas] 3306" from the command prompt, and it should connect and print a few numbers and then some garbage. If it fails to connect, then Moose has no chance of working.
