Error Message when creating a sensor



When creating a new sensor " wmiexchangeserversensor " for our exchange server 2003, Queue: Number of messages, the following error message is displayed:

Microsoft Windows Server Standard Edition - No provider installed for specified class.

This is the same issue when adding the sensor " Queue: Size (Bytes) " from the WMI Exchange 2003 option.

No problems in the past, this has only started this morning.

Having the same issue with Windows Exchange 2003 and PRTG WMI Exchangesensor. Using PRTG Version My Sensor whas working until 21.6.11 then offline. Try'd to clone and renew sensor, no success.

No changes on Exchange Server where done. Only thing, reboot from Servers... Rebooting PRTG, Sensor still down.

Any suggestions?

Thank you!

Please try to repair the WMI System on the target Exchange host.
