You need to check all the hardware and configurations. If you've never done that, I strongly recommend getting an expert in the door. Hardware configs, especially I/O, can be extremely tricky.
I agree with Grant.
There are windows settings, nic settings, maybe HBA configurations, san configuration, network devices (possibly), network paths (bad cables can cause this), bad disks, overloaded buffer, etc etc etc.
