A user is added to the wrong group on a client computer that is running Windows 7 or Windows Server 2008 R2

Applies to: Windows 7Windows Server 2008 R2


Consider the following scenario:
  • In an Active Directory domain environment, you use Group Policy Preferences to add a user to one of the following built-in user groups:
    • Cryptographic Operators
    • Event Log Readers
  • You apply the Group Policy Preferences setting to a client computer that is running Windows 7 or Windows Server 2008 R2.
  • You check the configuration on the client computer.
In this scenario, you notice that the user is added to the wrong group. Additionally, if the user is added to the Event Log Readers group, an error is logged in the Application event log:
Event ID 4098
Error: No mapping between account names and security IDs was done


This issue occurs because the groups.xml file on the sysvol share in the policy directory has the wrong security identifier (SID). Therefore, the SID does not match the group name.
