Is your supervisor higher than the IT guys? Let him know about the "issue" and he'll straighten things out with them or can their @$$es! 😃
Or if he's not above them, or he won't do it, then you're pretty much out of luck. Even using a MSACCESS database, you still need some sort of server-side script to access access (pun intended 😃). One thing you can do is forgo a web application entirely - Access supports Visual Basic and controls and the like, so you can program Visual Basic logic, and still use SQL queries for the Access DB.
