Did I go too Far?

You didn't do anything wrong unless you voided a warranty on the machines. Even then. Who's going to tell?

Some IT people working with a company will cover ignorance when it comes to solving problems. When someone else solves it, it makes them look bad and they get mad about it. I've been in your place before at different companies. Found it useful to get to know the IT folks and develop a decent relationship with them. Once they realize you are not trying to make them look bad, they may ease up.

Or, you could find an ally higher up than they are and put the pressure on them.

Or, you could find a job somewhere else.
