To install a new domain tree by entering unattended installation parameters at the command line

  1. At a command prompt, type the following command, and then press ENTER:

    dcpromo /unattend /<unattendOption>:<value> /<unattendOption>:<value> ...


    • <unattendOption> is an option in the Promotion Operation table. Separate each <option:value> pair with a space.

    • <value> is the configuration instruction for the option.

    The following example creates the first domain controller in a new domain tree where you expect to install at least some Windows Server 2003 domain controllers:

    dcpromo /unattend /InstallDns:yes /ParentDomainDNSName:<> /replicaOrNewDomain:domain /newDomain:tree /newDomainDnsName:<> /DomainNetbiosName:<trey> /databasePath:"<e:\Windows\ntds>" /logPath:"<e:\Windows\ntds>" /sysvolpath:"<e:\Windows\sysvol>" /safeModeAdminPassword:<FH#3573.cK> /forestLevel:2 /domainLevel:2 /rebootOnCompletion:yes

  2. When you have typed all the options that are required to create the child domain, press ENTER.
