I receive emails for minor problems and cell calls when its serious. I VPN in and this wotks for 95% of the problems. When I have to go in, luckily I live only 5 blocks from work.

Of course when far away on vacation and can't fix via VPN, a long process of talking a staff person through the fix process. Am in the process of having an external vendor provide on-site emergency help but rural Maine limits choices.

I connect with my laptop or home desktop. Have been very lucky that a major failure has not ocurred while on a far away trip.
