My favorite aspect of this is that enterprise support is often very bad and unknowledgeable about the product if you try to do something that's the least bit uncommon or outside their script.
You would think people focused on knowing just one product would know something about it.
Not at all - they know shit. Unfortunately "enterprise software companies" hire the lowest bidder in the lowest bidding country and they hire the lowest bidding staff.
This is especially true of Microsoft who I've had the pleasure of dealing with their highest level of Gold Partner support with respect to an IE9 bug that broke ClickOnce entirely.
Basically: absolutely fucking useless, blame the client, wriggle out of having to do anything.
That was until they met me. 35 phone calls (I shit you not), 3 heated arguments, spread bad press all over stackoverflow and MS connect, blog whinge and finally a half arsed registry fix that we had to deploy across 2000 disparate clients!
6 fucking months it took and we're a MS Gold Partner. It cost us more than our subscription cost in bad rep, time and support costs.
