Problem with installing MinimWatch

[Ketonjo]

Thanks Simon and BlueDog for getting back to me.

I've disabled and then enabled the Windows Firewall which seems to have made a difference as the icon in the system tray has turned green (however the icon on the desktop is still grey - should it be this way?).

Yes, I have pinged the NAS to the computer so from what I understand is that the NAS IP is the same as the PC IP? I've put the public IP address in the ohnet.subnet field replacing the last digit with a "0" but it hasn't made a difference. The last three digits are 172 so I entered it into the ohnet.subnet field as "170". At the moment this field is empty.

When I double click the icon on the desktop nothing happens. Any ideas as to where I go from here?

Cheers
John
