The issue is very likely with the policy on the TMG Server dropping the WMI requests from the Orion server. Below are the prerequisites required to make the template function properly.
Prerequisites: WMI access to the target server. On the Forefront server in the Forefront TGM snap-in, you will need to allow monitoring performance counters and services from the SAM server with the following parameters in the Firewall Policy menu. Create the following access rule:
Rule: Allow;
From: Local Host,
SAM server;
To: Local Host,
SAM server;
For: All users;
Protocols: Microsoft CIFS (TCP),
NetBios Datagram,
NetBios Name Service,
NetBios Session,
RPC (all Interfaces),
TCP-10003-OUT.
where:
- SAM server is the IP address of your SAM server;
- TCP-10003-OUT is the manually configured protocol with the following parameters in your primary connections:
Protocol: TCP;
Port range: From 10003 to 10003;
Direction: Outbound.
Credentials: Windows Administrator on the target server.
