>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.

Thanks, I will check this out. If I find something in the OS for such setting, I will let you know.
