We have a remote site that has two domain controllers in addition to the two domain controllers in the main site. We need to take down the link between the two sites for approximately 3 days, however the two sites still need to operate independantly of eachother in this time.
What's the best way to prepare for this? Can I just take the link down for 3 days and everything will just work perfectly, and re-sync when they come back online?
We are going to avoid doing things like domain account changes and password resets while the link is offline.
