A. When you run DCPROMO.EXE to create your Windows 2000 domain one of the stages asks if you wish to weaken security to enable 4.0 servers to act as RAS servers. If you said No but later decide you require this enter the following command:
C:\> <b>net localgroup "Pre-Windows 2000 Compatible Access" everyone /add</b>
This creates a local group "Pre-Windows 2000 Compatible Access" and adds the everyone group to it. After entering the command you must restart the domain controller.
