All - After running for months successfully one of our production Samba servers began giving an error yesterday: "The format of the specified computer name is invalid". I turned up the logging and wbinfo -t produces the following: wbinfo -t checking the trust secret via RPC calls failed error code was NT_STATUS_INVALID_COMPUTER_NAME (0xc0000122) Could not check secret I have rejoined the domain (deleted the computer account), deleted tdb files, rebooted system and a few other smb.conf changes. None of them will correct the issue. What am I missing? The other Samba servers are fine. Any help would be GREATLY appreciated! Bob Dehn
