Geoff,
thanks for that info!!
That was news to me.
I've been using SBS 2003 for about 1.5 years and only knew about the DEVICE CALs not USER CALs. I have the limit, 10 devices and no need to add another device. However I have only 6 staffers including myself. If I need to add other computers, could I switch the CALs to a USER model instead of current DEVICE model?
