I remember reading a tip where if you click on the gray text displaying the name of your computer on the login box, it gives you more information, like your IP address, the time, and the build and version of OS X. What I don't understand is the information followed by a red bubble stating "Network Accounts (or Users, I forgot) Not Available". What does this mean? Does it have something to do with me not having the Xserve version of OS X or ARD?
