Impact on physcial machines and network when running Capacity Planner.

Question

I need to find a white paper or an app note that explains how Capacity Planner collects data from physical machines.  I seem to have been pulled into the middle of a squabble between IT staff members that has the manager halting a virtualization project.  I have a virtual server running the Collector for Capacity Planner for 157 machines discovered in the customers network.  The Collector has been working fine, I am getting the inventory data I need to get on all systems except one.  At the request of the customer, I disabled the host name mask so we could see real host names in the report.  I also disabled the WMI checking since it only worked on half of my customers machines.  Using the Registry setting has gotten the inventory on all machines except one.  This one machine (an email server) has very strict administration control that is preventing the Collector service user from connecting.  When my contact and I tried to gain the needed access, our project was halted because the email server admin report an enormous amount of connection attempts from the Collection server that caused an issue with the mail server (was never able to get specifics on the issue).  This caused the manager to error on the side of caution and halt the project since the mail server admin believed the Collector caused his server issues.  My contact and I will be removing the mail server from the virtualization project, but to get the manager to allow the project to continue, I need to put something in her hands that explains how the Collector is getting it's data.  I have tried my self explaining it, but she is insisting on something from VMWare that explains how the collector is getting the data.  I know it is active collection, and as far as I know it just uses the built in WMI or Remote Registry services to request monitoring data that causes no impact to system performance.  I will be searching for an app note or a white paper or a KB article today, I would greatly appreciate if someone already knows of something that can settle this argument for me and help me get this project back on track.
thank you

Almost same setting here, same troubles.
If I restart them via Screen Sharing via the Restart Button on the Login Window, they sometimes show up correctly. But this is way too annoying.
