Since this morning shortly before midnight, all of my WMI sensors fail with the error "Connection could not be established (8002802B: Element not found - Host: gheterm2, User: ghesrvacc, Password: **, Domain: ntlmdomain:soi.dir.solutia.com) (code: PE015)"
I have looked in the knowledgebase and tried to find some reasons why these suddenly fail. I have rebooted Domain controllers, the paessler servers, checked WMI and WBEM, security, accounts and passwords. I found nothing wrong. I also tried the WMITEST utility from Paessler and could not find any problems. For instance, when i test the above sensor with the same credentials and requesting the same info (bandwidth), the system just returns the right data.
What else can I check ?
