UNIX Unable to See W2K Shared Printer

We have a SCO UNIX server on our Windows NT 4.0 Network and we have set up local printers attached to Windows clients as Remote Windows Printers for the UNIX application to access the printers. I need to replace one our W95 clients with a Windows 2000 Pro PC, but I can’t get the UNIX Server to see the shared printer on the Windows 2000 local port. I am guessing it is something in the Windows 2000 Pro security settings that is prohibiting the UNIX server from seeing the share, since the same scenario works if the client is a W98 or W95 PC. If anyone has any suggestions or solutions, it would be greatly appreciated.
