we have a client network and are about to install a new physical domain controller server 2012. We would like to create a backup domain controller as well , perhaps using one of there older decommissioned servers. Will having a physical primary DC work alongside a virtual backup DC. What softawre should we be considering pleasE?
also general question, client has office 365 but the 50 odd users access the fileserver onsite (which is part of the DC). Do we need users CALs for filesharing?
