Please help with quickbooks linking to LAN

I have installed quickbooks point of sale and accounting edition. Running smoothly on one computer.
I have connected it to 2 other comps via a lan connected to Dlink…
However i can give each computer access to the main server which ive shared local disk c. But they cant open the quickbokka software. Please help

error ni gani? is the quickbooks installed kwa server? does quickbooks licensing allow shared licensing? Does quickbooks have a special license for shared server installation?

Might it be cause its a cracked version?
