cause just like how every windows pc is its own environment (different hardware, anti virus, installed software, firewall settings, profile settings etc.) as well as you have different OS's (when it comes to servers there are as many set up's as there are linux distro's and you also can include window server OS and there are even some other custom OS solutions) so basically it comes down to what is running on the rack and the hardware.
all techies can do is make educated guessed based on what can happen based on the information given. If the techies were given the error logs you could bet your next gold/raid item they could find it in a matter of a few min to an hour or 2, cause if nothing else when techies get in a room stuff gets done as they will split up the load.
