I can mount Win 2003 shares on my Macs fine. However, the shares disappear after a while. This behavior is unlike on XP where the mounts stay attached forever. The session timeout on 2003 doesn't matter. It works that way out of the box, and after reconfiguring samba on the MAC to join the windows domain. I think it happens when the MAC goes to sleep and after waking up tries to remount the files systems. I get various messages in the system log: mount_smbfs: error from NetrShareEnum call: exception = 382312522 Dec 10 15:58:28 PowerBook kernel[0]: AFPSleepWakeHandler: waking up Dec 10 15:58:29 PowerBook configd[29]: AppleTalk startup complete Dec 10 15:58:29 PowerBook kernel[0]: smb_iod_sendrq: TRAN_SEND returned fatal error 32 Dec 10 15:58:29 PowerBook KernelEventAgent[37]: tid 00000000 received unknown event (33) Dec 10 15:58:29 PowerBook kernel[0]: smb_iod_sendrq: TRAN_SEND returned fatal error 32 Dec 10 15:58:29 PowerBook KernelEventAgent[37]: tid 00000000 type 'smbfs', mounted on '/Volumes/BUDZIANOWSKI;HOME-1', from '// BUDZIANOWSKI;ROMAN@HOME/DOWNLOADS', dead Dec 10 15:58:29 PowerBook KernelEventAgent[37]: tid 00000000 found 1 filesystem(s) with problem(s) Dec 10 15:58:29 PowerBook KernelEventAgent[37]: tid 00000000 received unknown event (49) Dec 10 15:58:32 PowerBook DirectoryService[47]: Active Directory: Could not determine closest Domain Controller from Site information in directory Dec 10 16:00:08 PowerBook kernel[0]: smbfs_smb_qfsattr: (fyi) share 'NTFS', attr 0x700ff, maxfilename 255 Dec 10 16:00:08 PowerBook kernel[0]: smbfs_aclsflunksniff: group sid S-1-5-21-1060284298-507921405-1801674531-513 didnt map Did I configure 2003 incorrectly (though it doesn't show on XP clients)? Or is this a samba problem on OS X? This is very annoying as some apps (iTunes) change their storage directory behind the scenes when a drive disappears.
