I have a brand spanking new 15" powerbook with Superdrive. I also just purchased the new Air Tunes Express. I work in a school that is all PC (except for our grading program made by Apple). The school uses a Windows server that requires me to log on with a special username and password. I know that my small-minded tech guy at school will tell me he can't do it (more likely...won't do it). How do I connect up to this thing? If I need more info, I can find it out. There is a firewall program but I don't know what it's called. ANy ideas?
