The command-line help for the DSMOD PARTITION command, a Active Directory command-line tool, is incorrect. When you type DSMOD PARTITION /?, you receive:

<b>Modifies attributes of one or more existing partitions in the directory.

dsmod partition <PartitionDN...> \[-qdefault <Value>\]
\[-qtmbstnwt <Percent>\] \[\{-s <Server> | -d <Domain>\}\]
\[-u <UserName>\] \[-p \{<Password> | *\}\] \[-c\] \[-q\] \[\{-uc | -uco | -uci\}\]
<PartitionDN...>      Specifies the distinguished names of one or more
                      partition objects to modify. If values are omitted,
                      they are obtained through standard input (stdin) to
                      support piping of output from another command as
                      input of this command.
-qdefault <Value>     Specifies that the default quota for the directory
                      partition be set to Value. The default quota will
                      apply to any security principal (user, group, computer,
                      or InetOrgPerson) who owns an object in the directory
                      partition and for whom more specific quota
                      specification exists. Enter -1 to specify an unlimited
                      quota.
-qtmbstawt <Percent>  Sets the percentage by which tombstone object count
                      should be reduced when calculating quota usage. The
                      percentage is specified by <Percent> and must be
                      between 0 and 100. For example, a value of 25 means
                      that a tombstone object counts as 25, or 1/4, of a
                      normal object when calculating quota usage. If a user
                      were assigned a quota of 100, that user could own a
                      maximum of 100 normal objects or 400 tombstone objects
                      in Active Directory.
\{-s <Server> | -d <Domain>\}
                      Connects to a specified remote server or domain. By
                      default, the computer is connected to a domain
                      controller in the logon domain.
-u <UserName>         Specifies the user name with which the user logs on to
                      a remote server. By default, -u uses the user name with
                      which the user logged on. You can use any of the
                      following formats to specify a user name:
                        user name (for example, Linda)
                        domain\user name (for example, widgets\Linda)
                        user principal name (UPN)
                          (for example, Linda@widgets.microsoft.com)
-p \{<Password> | *\}   Specifies to use either a password or a * to log on to
                      a remote server. If you type *, you are prompted for a
                      password.
-c                    Specifies continuous operation mode. Errors are
                      reported, but the process continues with the next
                      object in the argument list when you specify multiple
                      target objects. If you do not use -c, the command quits
                      after the first error occurs.
-q                    Suppresses all output to standard output (quiet mode).
\{-uc | -uco | -uci\}   Specifies that output or input data is formatted in
                      Unicode.
                      -uc   Specifies a Unicode format for input from or
                            output to a pipe (|).
                      -uco  Specifies a Unicode format for output to a
                            pipe (|) or a file.
                      -uci  Specifies a Unicode format for input from a
                            pipe (|) or a file.
Dsmod quota only supports a subset of commonly used object class attributes.

If a value that you use contains spaces, use quotation marks around the text
(for example, "CN=DC2,OU=Domain Controllers,DC=Microsoft,DC=Com").

The default quota applies to any security principal (for example, user,
group, computer, or InetOrgPerson) that creates an object in the directory
partition when no quota specification exists that covers the security
principal.

The default quota for a given directory partition is an attribute
(ms-DS-Default-Quota) of a special container of class
ms-DS-Quota-Container, as specified by CN=NTDS
Quotas,DirectoryParitionRootDN.

The tombstone quota weight for a given directory partition (set with the
-qtmbstnwt option) is an attribute (ms-DS-Tombstone-Quota-Factor)
of a special container of class (ms-DS-Quota-Container), as
specified by CN=NTDS Quotas,NCRootDN.</b>
The reference to -qtmbstawt <Percent> is incorrect. It should read -qtmbstnwt <Percent>.

NOTE: The description of the parameter is correct.
