The first thing I'd look at is auto-negotiation on your switch. It may be that your systems are having problems auto-negotiating their speed/connection type with the switch. Try setting the switch ports to work at 100Mb/s full duplex only rather than auto, and see if that cures the problem. If it does you can try 1000Mb/s to get the best connection. You only need to do this on ports connected to the PCs that are having problems.

It might also be worth dropping DLink a support request:
