Hmmm... 192.168.80.50 is inside the default range that Core will use for Pluto devices. Your Windows box should get an address in the 80.129 to 80.254 range (if you've left the defaults in place) and this address will be automatically allocated by the Cores DHCP server. Let the Core allocate it a valid IP for a non-pluto device and then the auto detection scripts should do the rest for you.
Thanks Andrew. I hadn't thought of that. I've statically assigned the IP of this box since it acts as a server for other functions, and it was .1.50 before, so I decided to just stick with .50 for the last octet. I did modify the DHCP range of Pluto before doing this, so that the range for MDs ends at .49.
So, if I'm to use Pluto to hand out an IP to this box so that it automatically detects Windows shares, how would I go about setting up a DHCP Reservation? I'd like its IP to always be the same, whatever that may be.
