Client Access LicensesPurchase a sufficient number of User CALs to cover all the employees in the organization. Only look at Device CALs in a shift-work environment where employees are sharing terminals.
Terminal ServicesIf terminal service access is needed, install and configure a separate terminal server computer on the network. SBS 2003 cannot run Terminal Services in Application mode.
Network configurationBuild the SBS server with two network cards and use a router/firewall device to connect the SBS server to the public Internet.
DHCP configurationUse the DHCP service from the SBS server and disable DHCP services on all other devices on the network (such as the router/firewall). Configure all workstations on the internal network to get a dynamic IP address from the DHCP service on the SBS server.
A highly generalized overview recommendation for the implementation of an SBS installation might look like this:
Network layoutA hardware router/firewall connects to the ISP for Internet access. An SBS server with two network cards connects the router/firewall and an internal switch. All networked computers, including wireless computers needing normal access to the SBS server, are connected to the switch.
Server storageThe SBS server has two spindles or partitions for data storage. The C: drive or partition is 12GB16GB in size. The data drive or partition is as large as necessary to accommodate the organization's data storage needs.
Backup storageIf using a tape drive for data backup and the capacity of the tape drive is less than the data size on the server, implement a third-party backup solution or customize a backup schedule using NTBackup (covered in detail in Chapter 18). If using removable disk drives, try to use a FireWire connection to an external disk enclosure with a drive large enough to store all the server data.
These are just guidelines. The actual implementation depends on the needs and restrictions of the installation site.
