I concur with Jesper, put in an IT ticket and then literally do nothing until you get an answer. Additionally, email your boss for record and let him know you submitted a ticket, you can't do anything until it gets addressed. He will either escalate it himself or if they don't answer, he will have to address it.
I deal with the same thing, IT operates with the right hand of God; Iron Fist style. Everything is locked down, no admin access, no admin rights for software, nobody gets sh_t (pardon my French). The best method is a cool head and smoke em' with friendship and kindness. Submit tickets and submit often...like....all the time.
IT ALWAYS plays god and always sees themselves as Corporate overlords. I understand their perspective but what they don't understand is your position. While they went to school for computer sciences, they didn't go to school for software communications, IO control systems and furthermore automation level integration. To that extent, it irks them why someone needs to have constant admin access, rights for software to be admin, registry editing capabilities, altering CPU level communication protocols...it's a HUGE NO in their field but from the needs of the business to succeed perspective...IT MUST BE DONE. The only way to get them to understand that is to constantly advertise submissions like, "I understand, please allow me to explain why I need it", "Allow me to help explain how this works.", "This can't operate without A & B.", etc.
They may still be like "Right hand of God, NOOOOO!" and that's fine. Submit a ticket....gets closed...submit another ticket, email the boss again stating tickets are ignored. Trust me my company IT has done this to me numerous times and I just keep politely knocking on the door, "Hey Bubba, how's it going baby! Looking sharp son!" It's a game of endurance, make them realize you're not going away...seriously. I have had my IT say I need to call the likes of Siemens, Wonderware etc. and tell them to rewrite their code to redirect drive storage locations and admin requirements...absolutely absurd to think they would, "Oh sure let me get right on that for one company with their head up...well."
IT simply doesn't understand the need and they never will until you force them to LEARN the situation and understand why you need it. They won't like it and will despise that your position overlaps with theirs as it's a HUGE security risk in their eye but eventually when managers are kept in the loop up top, eventually someone will remind them that they work for the company and the success is important, not their power trip. IT always acts as if they're an independent firm external from the company and that's bogus. Remind them how understanding and willing you are to work with them...constantly...again and again. Eventually like kids they will go, "Fine, whatever!"
That's my best advice for dealing with these matters and always keep your boss in the loop, make sure he is updated and has you back with support. Follow procedure, religiously lol. Worst case you eat bon-bons all day and watch programming videos or something educational for your time investment. Good luck!
