>>Over the years I've encountered many cases of spurious or unwanted Windows Event Log messages that simply cannot be disabled or fixed; MS itself has acknowledged many of them ("will be fixed in an upcoming version of Windows" but are never fixed for your current version).

>>If you're developing an Event Log monitor or dashboard you will need to have some way to store events that are known/confirmed to be spurious and which can therefore be ignored by your system. If and when you do that you can add these warnings about that particular cert to that database.

>And, we have. This is how I discovered it a few seconds after it was created. I think here, it is basically a question of having the ability to get those, or specific warnings like that, or not. When we control the situation, we usually do not want to be notified about things that we consider already resolved.

In this case, you really only want to stop event generation for one specific cert. You do NOT want to disable those warnings for other certs. So a registry key or similar won't work on a service level. The best you could hope for would be to go into your cert store, get the properties of the cert in the store and see if there's an attribute that can be set "Do not warn about expiration" or some such. I'm just speculating here, I know of no such attribute for individual certs.

Even if you can't "control the situation" for this particular cert, you already have the mechanism in place to ignore the events in your monitoring system.
