I'm a part-time DBA for our small shop. Up to now, our SQL Servers have all used mixed authentication for application compatibility. I have a new SQL Server that I'm spinning up now that doesn't require mixed. I know that using Windows Authentication is considered best practice for security (and this particular server needs to be as secure as possible), so that's the route I'd like to take.
However, I'm wondering... what would happen if the domain controllers became unavailable for some reason? Would no one be able to access the SQL Server? Or would my cached domain credentials on my workstation still allow me to connect?
I've googled around but I'm not finding a good answer as to what would happen in that situation, or I'm just not finding the right search terms.
