Zabbix server was unable to collect data because Microsoft did some hardening for DCOM and this changes are now enabled by default.

I have looked around the knowledge base and google search and nothing came up.  I wonder if you have encountered this already and created a KB article or patch somewhere. 

Steps to reproduce:

1. create external check script to use WMI to fetch info
2. create item 
3. attempt to fetch item data

Sample WMI query:

SELECT ProcessId, CommandLine FROM Win32_Process WHERE Name like '%java%' AND CommandLine like '%services=%'

Result:

WMI Query Failed

ERROR: Login to remote object.\n\n\n STDERR:\nNTSTATUS: NT_STATUS_ACCESS_DENIED - Access denied\n",), <traceback object at 0x7fab79734688>)

Expected:
No more WMI query errors
