Samba with Windows 2000 Professional

Hello all. I only want to configure my Suse linux 7.0 machine and Windows 2000 Professional to access from Win2000 to Linux. Not the printers. The printers are not important for me.From Win2000 I want to see the contents of the directory tree in linux machine. From windows 2000 I only see the Icon but when I double-click the icon a dialog box appears to tell me that I haven't permission to access to this machine. I login into linux as root and into Windows 2000 as Administrator. I don't know what happen because I think I setup all resourcess as public, browseable and writable. More public impossible, I think. The way to connect is as workgroup, not as domain. Thank you very much.
