One of my MF servers went kaboom today. When I boot it, I get an IO Error 000001 right after the OS Loader for NT4 pops up. I can log on locally, but a bunch of the services do not start (computer browser, Citrix services, etc;) and give an Invalid Address error. I've run some fairly thorough tests and am sort of lost. Rebuilding will take me a while and I want to make sure its really a software issue and not a hardware one. Any ideas?
