RPC Service - Problem with NIS09

Hello,

 

I have a problem with my NIS 2009.  I have the last version.

 

My problem is this:

 

-  I have the RPC service ON, in Windows (Vista Ultimate SP1), but Norton tell me that is off. I restart the computer, but the problem persists.

 

I contac the Norton Support, and i ran all procedure, but with no result.

 

Someone are having this trouble too?

 

Regards,
