I understand this is 5 years old, but it comes up in the first 3 on Google.
I'm doing the same thing - I was hoping to apply the new QoE to a few servers within my DMZ. Since I'm also not willing to GPO an RPC modification to several HA production servers, I was thinking about a secondary polling agent within my DMZ that can communicate back to the internal. How are others monitoring both sides of the firewall?
Thanks.
