Dashboard Problems

I have 2 HP COMPUTERS
1 24inch ALL IN ONE
The other HP Pavilion Laptop
WD DASHBOARD ON BOTH
Both are on a private network
On my PC the dashboard have picked up 1 WD RED 4TB drive connected via a docking cable

My laptop do not detect any drive at all
I have a multi HDD docking bay with a WD 2TB GREEN HDD
MY QUESTION
Why has it not been detected by the DASHBOARD?
As I have said both on my network with 2x4 NAS BAYS ALL POPULATED WITH WD RED NAS DRIVES (None detected by the DASHBOARD (Should they not be detected being on my same network?)
ANY HELP APPRIECIATED
THANK YOU
