network-based installation of Windows Operating Systems ( OS ) to reduce the complexity and cost of manual installation . This will require a WDS Server as a member of the Active Directory Domain Services ( AD DS ) domain . This also requires a Dynamic Host Configuration Protocol ( DHCP ) server with an active scope sine PXE relies on DHCP for IP addressing . Smart Card Authentication will require valid user principal names ( UPNs ) since they are required fo smart card login . Since a certificate authority ( CA ) will issue the domain controller certificates , the root certificate will be added to the Trusted Root Certification Authorities group policy in Active Directory .

This requires that WDS is configured so that it doesn ‘ t listen on Port 67 and DHCP option 60 will be used to notify a booting PXE client that there is a listening PXE server on the network . The server will also be configured to
