Or crap System admins. I've been working with Exchange for 4 years now and not once had a server fall over that wasn't user error.
No, this was for a massive corporate with all the MS bells & whistle support contract with a boat load of MS staff on site. It was in the 90's when their product was still in it's infancy and buggy as hell. It was a complete migration from Netware servers & Groupwise to MS products. Just be glad you weren't working on or using exchange back then.
