DHCP audit log files for IPv4 do not inherit permissions from their parent folder in Windows Server 2008 R2

Applies to: Windows Server 2008 R2


Consider the following scenario:

  • You install the Dynamic Host Configuration Protocol (DHCP) Server role on a computer that is running Windows Server R2.
  • You enable DHCP audit logging on the DHCP server.
In this scenario, the DHCP audit log files for IPv4 do not inherit permission from their parent folder. Therefore, you cannot access the audit log files remotely when you share their parent folder.


This issue occurs because the DHCP Server service sets a security attribute of the DHCP audit log files for IPv4 when the service creates the audit log files. This security attribute disables permission inheritance from the parent folder.
