I have had problems with this on FC3. I was never able to get it working under FC3. I performed the test by using cp. (cp -a /backup/temp.tgz smbclient D:\winxp box:) Linux: hda = PATA 100 80GB (IBM) Linux: hdb = PATA 133 160GB (SEAGATE) WinXP: C: = PATA 100 160GB (WD) WinXP: D: = SATA 150 200GB (MAXTOR) The only other protocol to try would be FTP or SFTP. I will try this also.
