Hi,
On several nodes (polling by WMI), I can't see Network Interfaces, CPU&Memory in List Resources.
What I can do to fix this problem?
Double check your windows user permissions and, if this still don't work, use the solar agent to collect data so you can see if the problem is WMI or your windows machine.
make sure the credential set on the NPM to poll WMI has full rights on the windows server. To troubleshoot, you wbemtest from the Orion server and use it to check if the credentials you are using is has sufficient rights to poll for CPU, RAM and interface stats.
If you haven't already looked at this guide, I recommend that you do

Resetting the WMI counters as explained in the doc will most likely help here
