Dear All, I am trying to set up a two way trust with a Win2k3 domain controller. The Win2k3 domain trusts the Samba domain with no problems but Samba will not trust Win2k3. The command, net rpc trustdom establish [Win2k3_domain], produces the following message after supplying the password: Could not connect to server [Win2k3_domain] [timestamp] rpc_client/cli_pipe.c:cli_nt_session_open(1451) cli_nt_session_open: cli_nt_create failed on pipe \wkssvc to machine [Win2k3_domain] Error was NT_STATUS_ACCESS_DENIED [timestamp] utils/net_rpc.c:rpc_trustdom_establish(4363) Couldn't not initialise wkssvc pipe I have two way trusts with other NT4 and Samba domain controllers working perfectly. wbinfo -m does not list the Win2k3 domain. My Samba setup is: RHEL3 Samba 3.0.9-1.3E.5 PDC/WINS/DHCP Thanks in advance for any help or suggestions. Andy.
