Connection could not be established (code: PE015)



We have a server with multiple sensors and all work with the exception of WMI Free Disk Space (Multi Disk) i have removed and re-added and even removed the whole server and re added and let it detect sensors - all which it detects work flawlessly - as soon as i add WMI Free Disk Space (Multi Disk) it doe snot work and says its down.

Using the Paessler WMI test tool i run all the WMI tests to the server and they pass including SELECT * FROM Win32_logicaldisk which shows free disk space normally.

Credentials are inherited from the parent and other sensors like CPU, PING and RDP show up fine.

any further hints?
