Server 2003 Licensing Modes & QuickBooks

I just installed & setup a new pc with Server 2003 to be used only as a
file & application server in a workgroup setting. There are only 10 pcs in
the network/office. I chose the per device/user licensing mode. The company
has QuickBooks Enterprise Edition licensed for 10 users. If I installed
QuickBooks with the QB database on the 2003 server, would there be any
problem with the workstations (all running XP Pro or XP Home) accessing the
database on the server?
The reason why I ask this is that the Server 2003 Licensing (CAL Terminal
Servers) confuses me. I do not think that using QuickBooks on the Server
2003 qualifies as a Terminal Service & therefore will be okay choosing the
per device/user licensing.
I really appreciate your input on this.

Thank you & happy holidays.
