I found this reference in a Technet article, talking about the Resource Kit tool RMTSHARE.EXE:
To Create Shares Remotely
To create or to delete shares on a remote server by using the Rmtshare.exe tool, use a command with the following syntax:rmtshare \\server[\sharename[=path [/printer]]] [/grant [user[:perms ]]] [/remove user][/users:number] [/unlimited] [/remark:"text"] /delete
An explanation of the syntax of the preceding command is:
The "\\server\sharename" syntax refers to boththe server and the share that you can create, inspect, modify, or delete.
The "/grant user:perms" syntax adds the name of a valid user or group on the server that have permissions, or changes the permissions of the user in an access control list. The valid permissions are: r=read, c=change (write), f=full, and n=none. You can type "read", but only the first character is used.
The "/remove user" syntax removes the specific entry for a user. Then, that user inherits permissions (in contrast to "/grant user:none" that denies any access to the user).
The "/users:number" syntax is the number of users that have privileges to the server and share.
The "/delete" syntax deletes the share that are specified by the "\\server\sharename" syntax.
NOTE : If a sharename or path contains spaces, enclose either the sharename or path in quotes, for example: \\server\"with space"="c:\with space".
hope this helps
