Steve,
I have a setup similar to yours. A pair of Switch 2000's with 100VG and
100BT fiber to various switching hubs, which then connect PC's, printers
and DTC's at 10Mb. The HP3000 is connected on a 10BT connection. This
works great. Even when the NT servers which are 100VG talk to the HP3000
the speed will just go to 10Mb.
