I have an XServe with 10.4 installed. The workstations are running a combination of 10.4 and 10.5. We just recently got a new iMac with 10.6. For some reason the iMac can access the server and create folders, but when I try copy a file from the desktop to the server, it does not copy. It just stays on the progress bar and never gets anywhere. Has anyone else had this problem. Is there a problem with an 10.4 Server with a 10.6 workstation? Do I need to upgrade my Server software? I have the 10.5 server upgrade software, but have just not gotten around to upgrading. If I upgrade to 10.5, should this resolve the issue, or do I need a server with 10.6?
