"The specified network name is no longer available."

Do you mean is the file being changed by the program? I'm actually not sure if the file gets changed at all, it appears to be a settings file that gets created during initial setup. All I really know is that they never had this problem with their old file server so I assumed it was something specific to the Readynas. The file isn't getting corrupted, it just becomes unaccessible. I'm thinking maybe it has something to do with the file getting locked?
