Network Access Protection Service - vista sp2

 
Now that I have the snipping tool working, I’m able to send a picture of my problem.
 
I’ve tried for two weeks to get it running.
 
If it isn’t running I can’t start Network Discovery.
 
This service is not working and I can’t get it to start. (Network Access Protection Service)
 
In an other attempt to get it to work, it seems to have something to do with (DEP)
