When you remove a member of a Global or Universal security group on a Windows Server 2008 R2-based domain controller, the MemberName attribute and the Account Name field are not populated in the security audit events. This problem occurs when you take any of the following actions:
  • You remove the member by using the user's security identifier (SID).
  • You remove the member from a group by using the Active Directory Administrative Center.
  • You remove the member by using the Remove-AdPrincipalGroupMembership Windows PowerShell cmdlet.

For example, you start the Active Directory Module for Windows PowerShell. To remove the user account "Audit1" in the Group1 Global security group, you use one of the following commands together with either the user's SID or the user's name:

PowerShell command using the users SID

PowerShell command using the users name

In this scenario, when you use either command, the MemberName attribute is not populated and is instead displayed as a dash (-) on the Details tab of the Event 4729 log. Additionally, the Account Name field is not populated and is instead displayed as a dash (-) on the General tab. The results are shown in the following screen shots.

The MemberName attribute is not populated and is displayed as a dash (-).

The Account Name field is not populated and is displayed as a dash (-).

  • This problem does not occur with the Domain Local group. The event always shows the MemberName attribute as the distinguished name, even if the removal is performed by using the member SID.
  • This problem can also occur in the Event ID 4757 log for the Universal group.


This problem occurs because the Windows PowerShell command uses the user's SID when the request is sent by using the Lightweight Directory Access Protocol (LDAP) regardless of whether the identity is passed as a distinguished name.
