Network Printer Setup giving error msg

I get the following error message after going through the standard printer driver setup in NT4.0 logged in as Administrator.
I see it in the list with UNC’s and am able to select it but when I select the INF (downloaded from brother) I get…
“Printer driver setup error: the printer driver is unknown”…I have a Brother HL-720 Laser Printer shared on the other computer (workstation).
