Good Morning, I have the some problem mapping printer ports on win98se. I think this problem ocurrs when a port is use by a printer, in example when i have a printer connected in lpt1, when i tried to map this port to a samba queue, it raises the error you told. Did you find any solution to this? It doesn 't happen on windows 2000, Windows xp. Thanks, Andr?s Yacopino Dpto Sistemas AcaSalud
