Whilst perusing my logs, ummmm, I came across this error:
CryptVerifyCertificateSignatureEx returned 0x80090006.
I have recently moved all the clients over to using a PKI certificate, as per this blog here, so I am very jumpy about certificate errors popping up.
The client seems to be okay though, so I did some googling… I came across this TechNet post.
TL:DR? It’s a good error, because it means self-signing isn’t working.
Perhaps we could go boldly and have an error if the PKI certificate isn’t working instead (see what I did there?), as opposed to an error something we are not using that isn’t meant to be working.
Wait, did you see? Split infinity… double negative? Okay 😛
