Introduction

Computers, that should be part of a Domain, have to join it. After this process they are members of the joined domain and able to access domain resources. During the join, an account for the machine will be created. This allows the computer to authenticate itself in the domain.

This documentation describes the join process as a Windows domain member to a Samba Active Directory or Samba NT4 domain.



System Requirements

Windows Version

To join a Domain, the Windows version requires the necessary capabilities. The following Windows versions are able to join a Domain as a member:

Workstation editions

  • Windows 10 Pro / Enterprise / Education
  • Windows 8/8.1 Pro / Enterprise
  • Windows 7 Professional / Ultimate / Enterprise
  • Windows Vista / Business / Ultimate / Enterprise
  • Windows XP Professional
  • Windows 2000 Professional
  • Windows NT4 (can only join NT4-style domains!)


Server editions

  • Windows Server 2012 / 2012R2
  • Windows Server 2008 / 2008R2
  • Windows Server 2003 / 2003R2
  • Windows Server 2000


Permissions

To join a client to a domain, you require

Ask your Domain Administrator for details.


Required settings for NT4-style domains

In case you're joining an Samba NT4-style domain, some settings may be required.



DNS Setting (AD only)

The client requies to have at least one DNS server configured, that is able to resolve names of the Domain it should join.

See DNS Configuration on Windows.



Date And Time Settings (AD only)

Active Directory uses Kerberos for authentication, which relies on a fairly consistent time across the network. This makes it necessary, that, before you can join the client to the Domain, the time on the client does not differ more than 5 minutes (default setting in an AD) to your Domain Controller.

  • Open the Control Panel.
  • Navigate to "Clock, Language and Region“.
  • Click "Date and Time“.

  • If the computer is able to connect to the Domain Controller / PDC, you will be prompted for credentials that are allowed to join to the domain.
