[Samba] Profiles -- default user ntuser.dat not being used at first logon
I'm trying to set up for my small school lab: Samba as PDC, 11 workstations running XP Pro, roaming profiles with folder redirection. (I finally got the workstations to join the domain by adding them by hand--so I assume something is wrong with my add machine script, but I'll address that issue later, since I have only the 11 XP boxes to deal with.) Now I'm working on getting the user profiles to work, based on TOSHARG chapter 23 plus Practical Exercises. But I'm not being successful, and I'd appreciate some help: My understanding is that when a user logs onto the domain for the first time, Windows should copy the default profile from the NETLOGON share on the Samba machine. (If this understanding is erroneous, please explain wherein I've misunderstood.) I have added the Samba user "tobedeleted", and put an ntuser.dat file for a default user in the /var/lib/samba/netlogon directory, which is the path I specified in the [netlogon] share, but Windows gives an error to the effect that the user's profile can't be found on the server, and that it will therefore create a local profile. Here's the relevant section of the samba log file for that machine: [2005/08/30 13:39:43, 0] lib/util_sock.c:write_socket_data(430) write_socket_data: write failure. Error = Connection reset by peer [2005/08/30 13:39:43, 0] lib/util_sock.c:write_socket(455) write_socket: Error writing 4 bytes to socket 25: ERRNO = Connection reset by peer [2005/08/30 13:39:43, 0] lib/util_sock.c:send_smb(647) Error writing 4 bytes to client. -1.

Error was Transport endpoint is not connected I'm puzzled by the "couldn't find service var" message. Is "var" supposed to be a service? I thought it was a directory.
