Unmanaged Detector SEPM 12.1.2 does not display information

Hello.

I am using the Umanaged Detector feature of the Symantec 12.1.2, to detect that teams not being administered from the console.

Enable this service on a client computer on my network, following the instructions in the KB http://www.symantec.com/business/support/index?pag... and but I can not have data on these computers.

Someone can tell me that can happen, or do I do to make this work.

The computer that is running as Unmanaged Detector is Windows 7 and the antivirus client version is 12.1.2015

Thanks for your help.
