Hi, I have Windows server 2008 Standard 64x Active Directory installed in the Head Office. I have to centralize another 42 branches in SL. Except 3 branches, each branch contain below 20 PC's. And our WAN link is 128K for each branch. So can i connect each branch's >20 PC's to the Head Office DC and ADC by balancing their load. Or do i need to put ADC for each an every branch?
