Domain - Query the Primary Domain Controller (PDC) of
domain.
You can also use \\Servername to specify the machine where
user accounts are created or read.
AddUsers will use the local computer by default (if you do
not specify
Domain)
/c
- Create user accounts, local groups, and global groups as
specified by
filename.
/d{:u} - Dump user accounts, local groups, and global groups to
filename.
The (:u) is an optional switch that causes current accounts to be written to the specified file in Unicode
text format. Choosing to dump current user accounts does not save the account's passwords or any
security information for the accounts.
Note: Password information is not saved in a user account dump and if you use the same file to create
accounts, all passwords of newly created accounts will be empty. To back up security information for
accounts, use a Tape Backup.
/e - Erase the user accounts specified in the file name.
CAUTION: Be careful when erasing user accounts, as it is not
possible to recreate
an account with the same SID. This option will
not erase built-in accounts.
Password_options
/p: - Set account creation options, used along with any combination
of the following:
* l - Users do not have to change passwords at next logon.
* c - Users cannot change passwords.
* e - Passwords never expire. (implies l option)
* d - Accounts disabled.
By default, all created users are required to change their
password at logon.
Example
Create a comma-delimited text file, which contains the new users to be created. Following the Syntax as
follows:
[Users]
User Name,Full name, Password, Description, HomeDrive, Homepath, Profile, Script
e.g.
[User]
jimmye,James Edward Phillip II,,,,,,
alexd,Alex Denuur,,,E:\,E:\users\alexd,,
ronj,Ron Jarook,ChangeThis,,E:\,E:\users\ronj,,
sarahs,Sarah Smith,,,,,,
u0123,Mike Olarte,,,,,,
Save the file as C:\Users.txt and execute the command
AddUsers MyDomain /c c:\Users.txt /p:e

ARP.exe
ARP - Address Resolution Protocol
Display and modify the IP-to-Physical address translation tables
used by address resolution
protocol.
Syntax
View the contents of the local ARP cache table
ARP -a [
ip_addr] [-N
if_addr]
Add a static Arp entry for frequent accessed hosts
ARP -s
ip_addr eth_addr [
if_addr]
Delete
an entry
ARP -d
ip_addr [
if_addr]
Key
-a Display current ARP entries.
May include more than one network interface.
If ip_addr is specified, the IP and Physical
addresses for only
the specified computer are
displayed.
-g Same as -a.
-N
if_addr Display the ARP entries for the network interface
specified
by if_addr.
-d
ip_addr Delete the host specified by ip_addr.
-d * will delete all hosts.
-s Add the host and associates the Internet address
ip_addr
with the Physical address eth_addr.
The Physical
address is
given as 6 hexadecimal bytes separated by hyphens. The
entry
is permanent.
eth_addr Specifies a physical address.
if_addr If present, this specifies the Internet address of the
interface whose address
translation table should be
modified.
If not present, the first applicable interface will be
used.
If two hosts on the same sub-net cannot ping each other successfully, try running ARP -a to list
the addresses on each computer to see if they have the correct MAC addresses.
A host's MAC address can be checked using
IPCONFIG
. If another host with a duplicate IP
address
exists on the network, the ARP cache may have had the MAC address for the other
computer placed in it. ARP -d is used to delete an entry that may be incorrect.
