Imbeded Windows 10 (IOT). We recently received a batch of these and are trying to configure them to burn an image. When trying to access our secure server we get a security problem with IE saying the certificate is bad. However, we have approximately 50 of the T520's running Win 8 with the same certificate with no problem. I have been over and over the configuration and can find no problem, but there is probably something I am missing, so anyone with some insight as to what I am missing I would gladly appreciate the help.
