Hi, I know this thread is old, but right now I'm having this problem about the Not Healthy Status of not only Network Security, but also of Teredo Server and Teredo Relay on one UAG server in an UAG Array. I checked the netsh ipsecdosprotection show interfaces, but I don't get that "Element not found" error.

I get a list of the public and internal interfaces, so I'm guessing that's not the problem, any ideas?

Thanks!
