I'm the author of Astralite. If you can't use Astralite find anything, there may because you didn't enter a password to access the remote Astralite server. It can be done in Astralite's preferences.
I highly suggest you use this app if you need to access files on mutiple Macs over a local area network.
If you have any questions, feel free to contact me via email. Thank you for using Astralite.
