Implementing CIFS: The Common Internet File System

This section lists all of the valid values for Status.DosError.ErrorClass, and most of the error codes for Status.DosError.Error. Additionally, a mapping between STATUS codes and DOS errors are provided.

The following error classes may be returned by the server to the client.

Class Code Comment ======= ===== ======== SUCCESS 0 The request was successful. ERRDOS 0x01 Error is from the core DOS operating system set. ERRSRV 0x02 Error is generated by the server network file manager. ERRHRD 0x03 Error is a hardware error. ERRCMD 0xFF Command was not in the "SMB" format.

The following error codes may be generated with the SUCCESS error class.

Class Code Comment ======= ===== ======== SUCCESS 0 The request was successful.

The following error codes may be generated with the ERRDOS error class.

Error Code Description ====== ===== ============ ERRbadfunc 1 Invalid function. The server did not recognize or could not perform a system call generated by the server, e.g., set the DIRECTORY attribute on a data file, invalid seek mode. ERRbadfile 2 File not found. The last component of a file's pathname could not be found. ERRbadpath Directory invalid. A directory component in a pathname could not be found. ERRnofids 4 Too many open files. The server has no file handles available. ERRnoaccess 5 Access denied, the client's context does not permit the requested function. This includes the following conditions: invalid rename command, write to Fid open for read only, read on Fid open for write only, attempt to delete a non-empty directory ERRbadfid 6 Invalid file handle. The file handle specified was not recognized by the server. ERRbadmcb 7 Memory control blocks destroyed. ERRnomem 8 Insufficient server memory to perform the requested function.

ERRdiffdevice 17 Not same device (e.g., a cross volume rename was attempted) ERRnofiles 18 A File Search command can find no more files matching the specified criteria. ERRbadshare 32 The sharing mode specified for an Open conflicts with existing FIDs on the file. ERRlock 33 A Lock request conflicted with an existing lock or specified an invalid mode, or an Unlock requested attempted to remove a lock held by another process. ERRfilexists 80 The file named in the request already exists. ErrQuota 512 The operation would cause a quota limit to be exceeded. ErrNotALink 513 A link operation was performed on a pathname that was not a link.

The following error codes may be generated with the ERRSRV error class.

Error Code Description ====== ===== ============ ERRerror 1 Non-specific error code. It is returned under the following conditions: resource other than disk space exhausted (e.g. TIDs), first SMB command was not negotiate, multiple negotiates attempted, and internal server error. ERRbadpw 2 Bad password - name/password pair in a Tree Connect or Session Setup are invalid. ERRaccess 4 The client does not have the necessary access rights within the specified context for the requested function. ERRinvtid 5 The Tid specified in a command was invalid. ERRinvnetname 6 Invalid network name in tree connect. ERRinvdevice 7 Invalid device - printer request made to non-printer connection or non-printer request made to printer connection. ERRqfull 49 Print queue full (files) -- returned by open print file. ERRqtoobig 50 Print queue full -- no space. ERRqeof 51 EOF on print queue dump. ERRinvpfid 52 Invalid print file FID. ERRsmbcmd 64 The server did not recognize the command received. ERRsrverror 65 The server encountered an internal error, e.g., system file unavailable. ERRbadBID 66 (obsolete) ERRfilespecs 67 The Fid and pathname parameters contained an invalid combination of values. ERRbadLink 68 (obsolete) ERRbadpermits 69 The access permissions specified for a file or directory are not a valid combination. The server cannot set the requested attribute. ERRbadPID 70 ERRsetattrmode 71 The attribute mode in the Set File Attribute request is invalid. ERRpaused 81 Server is paused. (Reserved for messaging) ERRmsgoff 82 Not receiving messages. (Reserved for messaging) ERRnoroom 83 No room to buffer message.(Reserved for messaging) ERRrmuns 87 Too many remote user names.(Reserved for messaging) ERRtimeout 88 Operation timed out. ERRnoresource 89 No resources currently available for request. ERRtoomanyuids 90 Too many Uids active on this session. ERRbaduid 91 The Uid is not known as a valid user identifier on this session. ERRusempx 250 Temporarily unable to support Raw, use MPX mode. ERRusestd 251 Temporarily unable to support Raw, use standard read/write. ERRcontmpx 252 Continue in MPX mode. ERRbadPassword 254 (obsolete) ERR_NOTIFY_ENUM_DIR 1024 Too many files have changed since the last time a NT_TRANSACT_NOTIFY_CHANGE was issued ERRaccountExpired 2239 ERRbadClient 2240 Cannot access the server from this workstation. ERRbadLogonTime 2241 Cannot access the server at this time. ERRpasswordExpired 2242 ERRnosupport 65535 Function not supported.

The following error codes may be generated with the ERRHRD error class.

Error Code Description ====== === ============ ERRnowrite 19 Attempt to write on write-protected media ERRbadunit 20 Unknown unit. ERRnotready 21 Drive not ready. ERRbadcmd 22 Unknown command. ERRdata 23 Data error (CRC). ERRbadreq 24 Bad request structure length. ERRseek 25 Seek error. ERRbadmedia 26 Unknown media type. ERRbadsector 27 Sector not found. ERRnopaper 28 Printer out of paper.
