workstations/laptops not communication with DC
So due to it coming up to the school holidays i have been thinking, laptop/workstations that dont contact the DC or are turned on in a long period of time (1-2 months) seem to drop off the domain and no one can log back onto them until they are re-added to the domain. now i believe this has something to do with the trust relationship between the computer and DC breaks down or something similar (i could be wrong).
so my question is, can i turn these computers off for 2 months then log on with an AD account when i first turn them on without removing and re-adding to the domain. Can i extend the trust relationship or something like that???
