Additional considerations

  • To perform this procedure, you must be a member of either the Account Operators group, Domain Admins group, or Enterprise Admins group in Active Directory Domain Services (AD DS), or you must have been delegated the appropriate authority. As a security best practice, consider using Run as to perform this procedure.

  • The user's primary group applies only to users who log on to the network through Services for Macintosh or who run Portable Operating System Interface for UNIX (POSIX)–compliant applications. Unless you are using these services, there is no need to change the primary group from Domain Users, which is the default value.

  • Setting the user's primary group membership to a value other than Domain Users may adversely affect performance because all users in the domain are members of Domain Users. If the user's primary group is set to another group, it may cause the group membership to exceed the supported maximum number of members.

  • You can also perform the task in this procedure by using the Active Directory module for Windows PowerShell. To open the Active Directory module, click Start , click Administrative Tools , and then click Active Directory Module for Windows PowerShell .

    To open the Active Directory module for Windows PowerShell in Windows Server 2012, open Server Manager , click Tools and then click Active Directory Module for Windows PowerShell .
