The sizing of the server will depend on the number of users.  We recommend running Total Info for larger groups of users in Terminal Server mode from a Microsoft Windows 2000 or 2003 server.  Terminal Servers should have at least a Pentium 4 processor, preferably at or above 2.8 GHz, 512 Mb RAM minimum (more with higher numbers of users), 100 Gig Hard Drive, 10/100 Mbps network interface card, Microsoft Windows Server 2000 or 2003.  Note: Total Info cannot be installed on a server running Microsoft Small Business Server.  When using Terminal Server mode, the network speed is not important and can be 10-Base T if necessary.  Also, there is no need to upgrade any of the user computers since the software will run exclusively on the server.
