I just installed leopard on one of my computers. I also have a mac mini which I'm using as a media server. After installing leopard on my laptop, I'm now unable to do a lot of things on my mac mini through my wireless connection, like change the names of folders, and my files. When I try to move a file it requires me to enter in a password, when I enter it, it does nothing. When I try to change a filename it says I do not have sufficient access privileges. Can anyone offer any advice on how to fix this?
