I have a project that's on the table and could be done a number of ways. It consists of a need for 30 workstations, all on a lan. I was considering using SBS 2003 on one box as the DC and another W2K3 box as a terminal server. The workstations would be 100% thin clients using a RDP connection to the terminal server.
The type of apps being run in at least 90% of the workstations would currently be a terminal (telnet) session to a unix box (legacy app) using an IBM terminal emulation tool (light weight). The remaining 10% would routinely use Outlook for email along with the gammut of Microsoft Office 2003.
My questions include (assuming no one dissents on implementing SBS/TS on a 2-box arrangement):
1) what do you think the adequate hardware would be for the servers to accomodate the 30 thin-client (potentially 100% simultaneous usage)?
2) In a terminal services environment (say, for 30 users), how would you expect antivirus licensing to be affected? One license on the server to cover/protect every session?
For the hardware I have in mind a dual proc Xeon with 2GB ram (room for 4 gb) and a couple of raid 5 arrays holding at least 120 GB each and possibly a NAS in addition but this is just a guess.
Any input anyone may offer is appreciated.
