Have 4computers on the network. One is Windows 2k3 SP1 Standard server and the other clients are WinXP. On the server there are 2NICs. The first NIC is connected directly to ADSL modem(not router or a hub) and second one is connected to SWITCH which has all 3 client PCs connected. The server's primary function is for Filesharing, ICS, Firewall, Peerguardian, P2P programs, DHCP&DNS Server What kind of tweaks should I apply to the server for maximum performance?
