Hi, I am now very confused. Can anyone explain what i actually need here??? We have windows 200 server installed as our PDC and BDC and would like to install another windows 2000 server as our terminal services server. To have group policy in active directory work do i need to use windows 2000 server or can i use 2003 server? 2nd question is what do i need to actually purchase for the licencing of the system? Obviously a copy of win2k b ut do i need to buy and TS CAL's? Does windows XP actually or 2000 server need addition al TS CAL's? Thanks
