All sensors suddenly went red



Hi, I'm working with a local probe and a remote probe, which were both in the same domain.

However, I have recently removed the local probe from the domain. (not sure if that matters though)

Basically today all of my sensors went error, only the local probe has a WMI delay of 750%. All the other servers don't have any error information included with the error.

The things that could have changed this:

- Today someone stopped the PRTG service on local probe (taskmanager) - Local Probe recently got removed from the domain - DNS name of Local Probe was changed, also in PRTG. (rename)

Not sure what the problem is! Please help.

Hi Sven,

A colleague is already taken care of this case via mail, so we won't respond here.

Kind regards,
