I've started with a company who has about 60 users, and are setup with two domains in their forrest (Parent and Child). They run 5 DC's total 2 in the parent and 3 in the child. I'm hoping to lessen the amount of servers they use here however I'm being told that it is essential to the stability of the network that we reamain using 5 dc's according to my predecessor. What I believe he may have been reffering to was in regards to the FSMO roles and not having the infastructure master on the same dc as a global catalog server which wouldn't be the case. Are their any other reasons why this would be? If more info is needed please let me know.
