Hello, I'm trying to integrate a samba server in 2003 AD. I've read different howto, And I've integrate computer with net ads join with success. Kinit user works fine. smbclient -k works fine too. But when I try to make a net use * \\server\share on a 2000 member server, I've the following error : error 1311 There are currently no logon servers available to service the logon request On any windows 2003 server it works fine !
