My first installation and NAS on a Pentium 4 with 3 GB RAM, one hard drive at 120 GB. Did the 32bit installation on USB thumbdrive. I can login from another computer to the GUI but nothing works, I can not change anything at all as in permissions, can't install plugins but I can copy and paste files on the volume from one computer to the NAS. I am a total n00b when it comes to this so please explain in terms a noob can understand! Using USF not ZFS
