You didn't say much about what O/S you're using, but generally speaking, IT departments that "lock things down" assign user privileges that don't include installation or execution of programs that are not on an approved list. Unless you want to get into cracking the admin password, which for the Windows family is possible if you look in the right places for the utility, you probably won't be able to install or run unauthorized software. BTW, cracking a password will get you immediately terminated at most places.
So how come you can't get into your parking spaces? Another phony "terror" alert?
