WMI NT code 0xc002001b, alerts for "Could not read Windows services" then clears

So every 10 minutes during our polling for Windows services a few of our servers gives us the error "Could not read Windows services" then the next time it polls the errors clear.

I use wmic on the Zenoss box and successfully query the devices.

The devices are all random Windows servers, 2003/2003 64-bit/ 2008 64/2008 R2.

Even when the device has the error, I can still go to 'Windows Services" and monitor a service, so it appears that communication is still working.

It is random boxes across several domains.

We did performance tunning on the Zenoss box and increased the scan interval.

Also we increased the scan interval and reduced the WMI services that we monitor.

Here is the error message in Zenwin logs.

We have restarted the server, we have removed Zenpacks;

We are potentially looking at the Enterprise version of Zenoss, but if we can't fix this issue we will have to move on to another monitoring solution.

Please let me know if there are any other troubleshooting I can do...

It could possible be something in the polling that is causing the issue, but I am kinda lost on where to look next.

Thanks
