I have about 12 sites connected throughout the city by frame relay. We run 2000/2003 mixed mode. Currently, we have a DC at every site we have. Apparently, the thinking was that "if there is no DC there, and the link goes down, they will still be able to log on".
However, I'm thinking that if the link is down, the only reason that they wouldn't be able to log on would be if they are a brand new user, or they are logging on to a machine they haven't used before. In addition, if the link is down (which is almost never is), they won't be able to do much at all, able to log on or not...
So, I'm considering simplifying the network some and demoting all the branch office DCs. I still have two at our hub site. I may keep another across one of the WAN links on our second largest site just so I will have another outside this building.
Am I missing anything I should consider?
