Answer 1

I use Zenoss to monitor my windows and unix boxes. The windows boxes are monitored though a combination of SNMP and WMI which doesn't require a agent on each of the system.

Here is a link to the zenoss community http://community.zenoss.org/index.jspa

Here is a link to the WMI ZenPack(plugin) http://community.zenoss.org/docs/DOC-3392

You can also join the IRC (Freenode #zenoss) for help.
