DJOIN Windows Command Guide

The Windows djoin command allows users to join a computer to a domain securely and efficiently. This command-line tool enables system administrators to automate the process of joining computers to a domain without the need for user interaction. By using djoin, administrators can join a computer to a domain during the deployment process, saving time and streamlining the setup of new machines.

The djoin command generates a blob file that contains the necessary information to join the computer to the domain. This blob file can then be used on the target computer to complete the joining process without requiring user input. This makes it ideal for large-scale deployments where manual domain joining would be time-consuming and prone to errors. Additionally, djoin supports unattended installations, making it a valuable tool for system administrators managing multiple devices.

When using the djoin command, administrators can specify various parameters to customize the domain joining process. This includes specifying the domain to join, providing credentials for authentication, and choosing the target computer name. By leveraging these options, administrators can tailor the domain joining process to their specific requirements and ensure a seamless integration of the computer into the domain.

Overall, the Windows djoin command simplifies the task of joining computers to a domain, making it a valuable tool for system administrators managing multiple machines. By automating the domain joining process and supporting unattended installations, djoin helps streamline deployments and ensures consistency across all joined computers.

DJOIN Command Samples:

Join a computer to a domain using the djoin command

djoin /provision /domain contoso.com /machine Comp01 /savefile join.blob

This command provisions the computer “Comp01” to join the domain “contoso.com” and saves the configuration in a file named “join.blob”.

Retrieve domain join metadata from a blob file

djoin /requestodj /loadfile join.blob /windowspath %SystemRoot%

Using the blob file “join.blob”, this command loads the domain join metadata into the system from the specified Windows path.

Provision a computer to join a domain without saving a blob file

djoin /provision /domain contoso.com /machine Comp02 /password <password> /passwordvalue P@ssw0rd!

This command directly provisions the computer “Comp02” to join the domain “contoso.com” using the provided password value.

Check if computer is eligible to join a domain

djoin /testodj /domain contoso.com /machine Comp03

Verifies if the computer “Comp03” meets the requirements for joining the domain “contoso.com” without actually performing the join operation.

Reset domain join metadata

djoin /reset

Resets all domain join metadata in the system, allowing for a clean start for domain join operations.

Display offline domain join blob information

djoin /showodj /loadfile join.blob

Shows the domain join metadata information stored in the blob file “join.blob”.

Export a provisioning file for offline domain join

djoin /exportprovfile /domain contoso.com /machine Comp04 /password <password> /passwordvalue P@ssw0rd! /savefile prov.xml

Exports a provisioning file named “prov.xml” for the computer “Comp04” to join the domain “contoso.com” with the specified password value.
