I have WMI sensors set on multiple servers. All are using inherited credentials. One DC is working fine with WMI, the other never gets a response after adding the sensor. All firewall settings are GPO set. I get the error Connection could not be established (80070005: Access is denied) (code: PE015). It appears that you are experiencing some difficulties with WMI or related areas. For more information, please see our knowledge base: https://kb.paessler.com/en/topic/60153
I cannot use the WMI tester as even on the servers that work the tester fails due to the locked down nature of the network. This is a Domain Controller so I can't just reimage a new server. This server is synced with all the exact same settings as the DC that is working just fine. So I know its not an issue with the firewall settings as they are identical, its not a user account issue as they are identical as well. They have the exact same patch schedule with the same patching policy and were both patched after the last patch Tuesday. I'm not sure what is causing the issue. Any help would be appreciated.
