Hi I am having problems with machine authentication on an NT workstation 4.0 SP6a client. The current version of samba is 2.0.4b complied on Sequent/Dynix 4.4.8. We are using "smbd" and "nmbd" as services launched from the inetd file. No restrictive or secure components have been enabled. The "smb.conf" simply has the appropriate mount options defined. The problem occurs when we attempt to establish a connection from the NT client. The NT registry entries have been updated for "EnablePlainTextPassword - DWORD -HEX - DATA 1" and the NT client has been rebooted several times. When we try this on alternative systems there are no problems and it works and maps with out any errors or issues. The NT systems reports the same error each time: Machine is not authorised to use this connection I have checked the samba configuration on other systems included new builds and no problems are experienced. It would be appreciated if you could throw some light on this problem. Is their something seriously wrong with the NT registry entries? Or am I doing something extreme wrong. Many thanks in advance Akeel Bhandari ICL-PATHWAY
