PRTG stopped talking to 6 servers this morning citing WMI connection could not be established. I'll buy 1 server having a WMI issue, but 6 all at once? Not even in this environment do I agree with that. This is clearly a PRTG problem that needs to be addressed.

It's likely that your probe machine's WMI is having the problems as WMI is very unreliable the more you try to monitor with it and the rate at which you request updates. If you check the probe health sensor you can see if its experiencing poor WMI performance.
If you can post the error message you get from PRTG that would be helpful too, or any from the eventlogs.
