I’m back again with one more PowerShell script, this time getting certificate expiration warnings from Windows machines.
You can use the PowerShell script below to create a template and get warnings, critical, down etc. if a certificate is close to expiration or already is expired.
Lately I had the issue that SolarWinds Orion was detecting an expiring certificate on one of our servers. I have replaced every certificate on the server and double checked (of thought!) that the old certificate was deleted. But it was still complaining about an expiring date on a certificate I couldn’t find. I checked the event logs and found the event 15021, which told me something was still wrong.
I found out that a certificate was on a binding with “netsh show http certssl” in a command prompt.
