NETDOM Join

Join a workstation or member server to the domain. In Windows 10 use the Add-Computer cmdlet instead.

Syntax
 NETDOM JOIN machine /Domain:domain [/OU:ou_path]
 [/UserD:user] [/PasswordD:[password | *]]
 [/UserO:user] [/PasswordO:[password | *]]
 [/PasswordM:[password | *]]
 [/ReadOnly] [/REBoot[:Time_in_seconds]]
 [/SecurePasswordPrompt]
Key:
 machine The name of the workstation or member server to be joined
 /Domain The domain which the machine should join.
 Specify a particular domain controller by entering
 /Domain:domain\dc. When /ReadOnly option is used, you 
 must specify a domain controller. 
 /UserD User account used to make the connection with the Domain of
 the machine to be managed
 /PasswordD Password of the user account specified By /UserD.
 Specifying a * will prompt for the password.
 /UserO User account used to make the connection with the Machine to be
 managed
 /PasswordO Password of the user account specified By /UserO.
 Specifying a * will prompt for the password.
 /OU Organizational unit under which to create the machine account.
 This must be a fully qualified RFC 1779 DN for the OU.
 If not specified, the account will be created under the default
 organization unit for machine objects for that domain.
 /PasswordM Password of the pre-created computer account, whose name is 
 specified by the machine parameter.
 Specifying a * will prompt for the password.
 This option must be used with /ReadOnly option.
 /ReadOnly Perform a domain join using a pre-created computer account and 
 without performing any writes to a domain controller. This 
 option therefore, does not require a writable domain controller.
 You must specify the domain controller (using /Domain option) 
 and computer account password (using /PasswordM option) 
 when the option is used.
 This option cannot be used with the /OU option. 
 /REBoot Shut down and automatically reboot the machine after the Join
 has completed. The number of seconds before automatic shutdown
 can also be provided. Default = 30 seconds
 /SecurePasswordPrompt 
 Use secure credentials popup to specify credentials. This
 option should be used when smartcard credentials need to be
 specified. This option is only in effect when the password 
 value is supplied as *

Windows Professional machines with the ForceGuest setting enabled (which is the default for machines not joined to a domain during setup) cannot be remotely administered. Thus the join operation must be run directly on the machine when the ForceGuest setting is enabled.

Joining a machine to the domain will create an AD domain account for the machine if one does not already exist.

Netdom options can be abbreviated to just the UPPER case letters, e.g. /PasswordD can be supplied as just /PD
