NET LOCALGROUP modifies local groups on computers. When used without
options, it displays the local groups on the computer.

groupname        Is the name of the local group to add, expand, or
                 delete. Supply only a groupname to view a list of
                 users or global groups in a local group.
/COMMENT:"text"  Adds a comment for a new or existing group.
                 Enclose the text in quotation marks.
/DOMAIN          Performs the operation on the domain controller
                 of the current domain. Otherwise, the operation is
                 performed on the local workstation.
name [ ...]      Lists one or more usernames or groupnames to add or to
                 remove from a local group. Separate multiple entries with
                 a space. Names may be users or global groups, but not
                 other local groups. If a user is from another domain,
                 preface the username with the domain name (for
                 example, SALES
ALPHR).
/ADD             Adds a groupname or username to a local group. An account
                 must be established for users or global groups added to a
                 local group with this command.
/DELETE          Removes a groupname or username from a local group.
