Tim, I presume that marking your post useful is totally redundant.
We use both Windows and Linux servers for our Moodles. Linux is infinitely faster and more stable. Windows is just not right for Moodle, though you can struggle through. We are.
I say your IT folks (probably guys) are being obstructionist. Nobody likes a system they don't understand. Upgrade carefully. 2.6 gives much improved performance, but you have to go through the assignment upgrade helper and a quiz upgrade (right, Tim?).
Be fortified to know, even though you aren't an IT, person that hardware is no longer a major expense! So don't be intimidated.
For dealing effectively with IT and getting them on your side, try talking to Mary Cooch. She's done it all.
