Hi, I've been looking for a solution to a problem that occurred a few weeks ago:
During an Internet outage the shared drives on the local Windows file server works perfectly until:
a) client reboots its computer
b) server is rebooted
c) clients go home, and the next day they come back to the office the shared drives authentication is no longer available
We use AD authentication and during the Internet outage no DC is available, so we rely on cached credentials (https://support.microsoft.com/en-us/help/172931/cached-domain-logon-information), but it is not a good solution for us if a), b) or c) occurs or if cached info is overwritten with other cached stuff or if client #51, #52, #53 tries to connect since some offices have more than 50 staff connecting to the server through shared drives.
Besides creating local accounts on my file servers and keep user/password in a safe central place and initiate access to them with a DR plan, do you know a better way to enable shared folders access during a long Internet outage with no Domain Controller access at all?
