SUBINACL.exe – Windows CMD Command

Display or modify Access Control Entries (ACEs) for file and folder Permissions, Ownership and Domain.

Access Control Lists apply only to files stored on an NTFS formatted drive, each ACL determines which users (or groups of users) can read or edit the file. When a new file is created it normally inherits ACL’s from the folder where it was created.

Syntax
      SUBINACL [/noverbose] /object_type object_name [/action=parameter] [/help]

Key
   object_type:  service        e.g.  /service Messenger \\ServerName\Messenger
                 keyreg         e.g.  /keyreg HKEY_CURRENT_USER\Software
                                      /keyreg \\Srv\HKEY_LOCAL_MACHINE\KeyPath
                 file           e.g.  /file *.obj  /file c:\test.txt
                                      /file \\ServerName\Share\Path
                 subdirectories manipulate files in specified directory and all subdirectories

   object_name : This will vary according to the object_type - see the examples above

   action      : setowner=owner
                 will change the owner of the object e.g. /setowner=MyDomain\Administrators

                 replace=SamName\OldAccount=DomainName\New_Account
                 will replace all ACE (Audit and Permissions) in the object
                 e.g. /replace=MyOldDomain\Finance=NEWDOM\Finance

                 changedomain=OldDomainName=NewDomainName
                 will replace all ACEs with a Sid from OldDomainName
                 with the equivalent Sid found in NewSamServer 
                 e.g. /changedomain=MyOldDomain=NEWDOMAIN
                 This option requires a trust relationship with the server containing the object.

  Help           Run SUBINACL /Help (or SUBINACL /Help /action) for more
                 detail on the many other options.

SUBINACL is a powerful command that can do everything cacls and xcacls can do and more besides.

When running subinacl against a subfolder, its important to include the trailing backslash, (or \*.*) if this is missed out subinacl will interpret the path as a filename and search the entire drive for it, this can be very slow!

Examples:

Save permissions to a log file:
subinacl /noverbose /nostatistic /outputlog=SS64.log /subdirectories "C:\Program Files\My Folder\*.*" /display

Restore Permissions from a log file:
subinacl /nostatistic /playfile SS64.log

Change owner :
subinacl /file C:\demofile.doc /setowner=SS64Dom\AliceT
