I'm currently in a Windows 10 domain environment that uses smart card authentication. We are using ActivClient 7.1.0.213 for reading the smart cards. I use a user smart card to login as a user (which has only user certificates on it.) I have a separate smart card for administrative tasks, which has its own certificate.
When I run a program as an administrator or connect to the network drive, a Windows Security prompt will appear asking for my credentials. At this point, there will be a small blue text link that says "More choices" at the bottom. Clicking this will enable me to pick a certificate from my smart card and then type in a pin.
The issue I am having, however, is that this "More choices" option seems to randomly disappear. Because of this, I am unable to select my certificate and thus cannot connect the network drive or run the program. The only solution so far I have found that works is to restart my computer.
What could be causing this and how can I troubleshoot/fix it?
