I have installed Samba 2.2.3a on a Solaris 2.6 box, and it has been configured with a small smb.conf that sets security = domain, workgroup = GFMNET, password server = GFMNET01, I have succesfully joined domain GFMNET (controlled by GFMNET01). I can attach to resources anywhere in the domain from this new box(E250), but any attempt to connect to its resources results in failed authentication. I earlier had 2.2.2 running on GFMNET01, but have just upgraded to 2.2.3a to match that on E250 (in case that was the problem). I also previously had "password server = *" on E250. It claims (in the log files) that it cannot find the password server so I specified GFMNET01, and still have the same error. I feel that the GFMNET01<Domain Controller> machine needs to authenticate itself to E250 even though E250 is using GFMNET01 as its' password server, but how would this be done? I could be barking up the wrong tree here... Anybody? The errors are as follows from running this on E250: smbclient //e250/SystemReports -U <Valid username> ====Begin snippet===[2002/02/12 20:00:22, 0] rpc_client/cli_netlogon.c:cli_net_auth2(157) cli_net_auth2: Error NT_STATUS_ACCESS_DENIED [2002/02/12 20:00:22, 0] rpc_client/cli_login.c:cli_nt_setup_creds(74) cli_nt_setup_creds: auth2 challenge failed [2002/02/12 20:00:22, 0] smbd/password.c:connect_to_domain_password_server(1336) connect_to_domain_password_server: unable to setup the PDC credentials to machine GFMNET01.

Any and all comments appreciated... Con.
