Cut the ground wire in your power cords but ground the equipment directly to a metal frame.i strongly recommend that you do this, especially in your 240vac environment. excellent solution to a lot of problems.
Don't even joke about doing this, please. If there is potential on the grounding conductor, then that problem needs to be corrected as it is a safety of life issue. Even if you cut the conductor and safely ground the equipment in that one rack, you are ignoring the fact that you have very strong evidence of a serious wiring problem in the form of destroyed equipment.
Say you do what you suggest, ensure that your rack is well and solidly grounded. And, you're aware that the building grounding wiring is defective. And then someone comes in (maybe you) and plugs in a piece of portable test equipment next to your nice grounded rack. And then puts one hand on the test equipment (plugged into one of the defective outlets) and the other on your well-grounded rack. Especially in the 240 volt environment.
There is a serious, potentially fatal, wiring fault in that building. Get it fixed properly.
