With what? :)
Anyway: you have *something* wrong with your topology or infrastructure
somewhere, clearly. I'd put my money on it being at layer 2 - a duff
cable, bad switch port, bad cable run (adjacent to power), wrong type of
cable (Cat5e where Cat6 should be, for example) and that you remove the
problem by going direct.
Is (Are) your director(s) [a] physically separate machine(s) from the
realservers?
Remind me again - this is DR, isn't it?
