Thanks to input from UT, I have my SAMBA daemon (demon, whatever) running on my Mandrake-Linux server "Bradbury" and authenticating using domain security to my PDC machine. I can connect to Bradbury from a network workstation running Microsoft Windows NT 4 workstation, and I can connect to it from the machine running Microsoft Windows NT 4 Advanced Server (to which it actually authenticates). On the NT workstation I was logged in with a NT username that also exists on Bradbury and I did not receive a username/password prompt. On the server I was logged in as administrator (an account that does not exist on the Linux box) and I suppose this is why I did receive a username/password dialog. Once I entered the appropriate username/password, I was granted access to the SAMBA share. However, when I attempt to connect to the SAMBA share from a workstation running Microsoft Windows 9x, I receive the dialog "\\Bradbury is not accessible. This device does not exist on the network."

Besides my amusement over the text of the error ("the machine on which you clicked does not exist"), I am all the more frustrated because it seems I am so close.

Can anyone suggest where I might look to determine why the Windows 9x machines cannot connect?
