Hello list, I have been using "smb ports = 445" to get rid of the dreaded "Transport endpoint is not connected" error, and it seemed to be working fine for Windows XP, on SerNet's samba3-3.3.9-40.el5 build. We recently introduced Windows 7 to our network - and the "Transport endpoint" errors are back: Nov 25 17:21:41 experimental smbd[13018]: [2009/11/25 17:21:41, 0] lib/util_sock.c:read_socket_with_timeout(939) Nov 25 17:21:41 experimental smbd[13018]: [2009/11/25 17:21:41, 0] lib/util_sock.c:get_peer_addr_internal(1676) Nov 25 17:21:41 experimental smbd[13018]: getpeername failed. Error was Transport endpoint is not connected Nov 25 17:21:41 experimental smbd[13018]: read_socket_with_timeout: client 0.0.0.0 read error = Connection reset by peer. Anyone know what Windows 7 is trying to do here? I'm also seeing some other errors generated by Win 7: Nov 25 17:21:18 experimental smbd[13018]: [2009/11/25 17:21:18, 0] rpc_server/srv_netlog_nt.c:_netr_ServerAuthenticate2(555) Nov 25 17:21:18 experimental smbd[13018]: _netr_ServerAuthenticate2: netlogon_creds_server_check failed. Rejecting auth request from client MEEPO machine account MEEPO$ It all works - I've joined the domain and can log in and access the shares, so obviously it does manage to authenticate somehow, so is there any way of stopping those messages appearing?
