I have an XServe G4 with Mac OS X Server 10.4.11. We have three internal hard drives, the system drive and two raided 500 GB drives. We use the RAID for file sharing. When we connect to the network drive and try to duplicate a file (or copy & paste a file), it acts like it is about to copy the file and then turns up a -50 error. I'm assuming this is a permissions problem but have no clue how to fix it. We can drag files to the server from other office computers and it will copy them just fine. It is only when we try and duplicate files already on the network drive. Thanks ahead of time for any insight on this.
