If memory serves I helped our IT guy replace the whole mess with Apache, so we’d never have to talk to them again. I used to compete with Netscape so there was no small amusement in costing them contractor hours.
In my very first consulting gig, my employer intentionally buried all of the best documentation on an internal forum. I can't even count all the hours I burned up on troubleshooting, only to learn days later that the thing I was encountering was a known issue that was completely undocumented and the only way to know that was to be present in the office... which was 3000 miles away.
I tried to get management to open up the forums to public consumption, but they were dead set against it, said that their "intellectual property was too valuable."
I've long ago learned that people misremember all the time. I trust the person who quickly looks up the correct answer in the manual over the person who thinks they din't need the manual and uses what they think is right. Sure often the second person gets things right, but when they get it wrong they waste a lot of time trying to figure out which thing is wrong.
Nothing they were doing was worth $250 an hour.
I once saw the original architecture document and it was actually very nice -- though perhaps unorthodox. The implementation was like an encyclopedia of Worst Practices.
I also worked a summer for IBM Global Services doing some sysadmin and security work back in 1997... I'd characterize the whole thing as... mediocrity.
Another time, I worked a contract in another part of IBM and saw other parts and got to attend presentations and lectures there and see the patents on the walls, and be exposed to some of the really smart people and history there, and that product side of the organization (people who worked on DB2, etc.) seemed much better.
