Network Topology Discovery – Windows 7 Via GPO

Question

I wish to enable Network Discovery on my network (For various reasons) I need to apply this via GPO due to the nature of our setup. This is on a Windows 2008 R2 Domain with Windows 7/XP Clients.

I have tried to enable this in the GPO and it shows the below;

> Network/Link-Layer Topology Discovery Policy  Setting Comment Turn on
> Mapper I/O (LLTDIO) driver Enabled     Allow operation while in
> domain    Enabled Allow operation while in public network Disabled
> Prohibit operation while in private network   Disabled
> 
> Policy    Setting Comment Turn on Responder (RSPNDR) driver Enabled   
> Allow operation while in domain   Enabled Allow operation while in
> public network    Disabled Prohibit operation while in private
> network   Disabled

But when logging onto the clients this isn’t applying. I have Run RSOP and the output isn’t showing that this has applied as well. Any comments would be appreciated
