APM picks up some IIS instances, not others.

Hi,
I have 2 near-identical servers that are running IIS.
APM picks up IIS on one using a simple SNMP template.
On the other, it keeps coming back with an error:
"Testing on node ......: failed with 'undefined' status: timeout"

IIS is fully functional on both boxes, OS, Patch, settings, etc, etc are identical.
I have restarted IIS, checked availability of the site from remote servers (including the Orion server. I can't find anything that would be causing this.

Thanks.

There was an odd problem with the SNMP service on the server.

It was still passing values on previously configured items like CPU & memory, but wouldn't pass data on any new request areas. I deleted all the settings , reinstated & restarted, and now all seems ok.

Is NPM picking up other statistics of the server via SNMP like CPU load, memory usage or volume space?
