So Today, I attempted to access my NAS over SMB (
\\files) on my network workgroup. The window hung for a moment, and a dialog I've never seen before when connecting to a share, with the title "Select Certificate" popped up. ultimately, I'm unable to access my shares from this box.
I can see that a certificate windows registered for my local user has expired. it was issued by me to me, the very definition of self-signed. The certificate has no trusted root certificate (not surprising). Windows tells me I have a private key associated with this certificate.
I did not knowingly create a certificate, and I've never known SMB to just fail every year just because a cert expired (or really even to require one at all, if you are not on a domain).
A reboot didn't clear the issue, and I'm having difficulties finding information on generating a suitable replacement.
It appears I can get to shares using the FQDN, without any request for a certificate. DNS resolution works as well for hostnames as fullnames on my LAN, so I'm thinking something has remembered that destination, and needs to be flushed. any ideas what?
