What is the best platform?
We are running these plugins in productive environment on probes like Windows XP (Pro x86), 2003 server family and 2008R2 servers.
Based on our experience XP x86 does not really suite for this but it works, well...somehow.
When making the decision between 2003 and 2008r2 probes make note of the target devices, it pays off the keep those on same level.
Especially if you have a lot of 2003 servers which you to monitor it makes sense to keep the probes on that level as well.
