Advice for the K12 Tech Guy?

small fish asks: "I am a newly dubbed 'Technology Coordinator' for a K-12 school district. Things here technology-wise are not well. People here are ignorant technology-wise--which is fine, as being tech-savvy is my job. However, they do not seem to trust my judgment on anything except changing printer cartridges. I'm being measured against a former teacher who filled the role for a while and was VERY comfortable with using Microsoft products. Are there any other Slashdot readers out there in similar straits? If so, what advice do you have for me?" "For starters, there is no firewall, all IPs are exposed to the public, they are relying on Windows NT 4 boxes to sustain operations, and they seem to love their Exchange for doing email and address books, although I have only one user who migrates between two different computers. The Exchange server died due to a spam overload and will not restart, so I set up a BSD box for handling mail and DNS. To make things worse, there is no real disaster recovery here and virtually no backup power. As I type my carpets are still wet from last night's rains that poured through the machine room wall - and this happens every time it downpours I'm told.

My coworkers do not want anything to do with Macintosh computers, they have never heard of Firefox, and Unix was a strange foreign word I had to explain to some before I gave up entirely. What tips do you have for surviving (even thriving) in this type of environment?"
