I have a Windows 2003 machine(2) with a share mounted on a Freebsd machine (1) via mount_smbfs Hardware Machine 1 FreeBSD pcmarpxy.mine.nu 4.9-STABLE FreeBSD 4.9-STABLE #1: Fri Jan 30 23:33:38 CET 2004 root@pcmarpxy.mine.nu:/usr/obj/usr/src/sys/MARK i386 PIII 650, 392mb ram system : ata-100 5400 disks on builtin ide data :- 2 ata-100 disks on a promise ata card running under vinum (software raid) raid 0 - real men always run raid 0 :-) BSD is recently cvsupped and compiled etc...=20 samba Version 3.0.1 Machine 2 Windows 2003 all patches.
