Ok thanks for that update. I think MS made it by design (in terms of making the expiration date that far in advance for the default root certificate) due to the fact that the cert is tied to some core services (backup, dashboard console, etc) and since the essentials version is tied to market SMB's, it's probably a pain to re-create the cert after x amount of years…just my 2 cents..
Anyways, it still seems to function even though I import it and it displays that PHP error..is it still safe to use (ie, for OpenVPN RA) and that I won't run into major issues or will the system crash or have some adverse effect from me from forcing pf to use a cert it can't half read?
