Just a quick post reflecting that a bug fix update for autodiscovery client has been posted under device42 autodiscovery download page.
The issue was in relation to this Microsoft article: http://support.microsoft.com/kb/932370/en-us
Basically if we were not able to get CPU information, it would throw “System.Management.ManagementException: Invalid query ” exception and not find/upload information for that device.
With v201, if the CPU info is not received, it still gathers other information for the device and uploads to device42 appliance.
You would need to uninstall v200 first to install v201.
