I am curious about something. It has been quite a while since i had any job that required me to think about DCs. Back in the day we would have a setup of regular modems. If all hell broke loose, then we could dial up a modem and have access to the system. It was not fast, and it was a pain, but we could get access that way. (I am skipping a lot of steps. There was heavy security involved in getting access) I guess landlines might not be an option anymore??
