Used to see this back in the Win3.x/9x days when video memory was low. Not sure in this case if that would be your clients or the TS servers, but maybe start with looking at memory?

We have two TS boxes, both the same, both running 2003. The last few days have caused users to see black blocks on the screen, sometimes in place of toolbar icons, sometimes covering entire windows. There doesn't seem to be an pattern, happens on multiple machines, over two servers etc. My worry is that it's going to be down a hardware fault or something. Anyone seen anything like this before?
