HI, We run a medical software across a network of computers. The server holds the server software and the clients all run clients versions of software. Hardware: Mac Mini quad core for server with sad Mac mini i5's for clients. Software Malpractice We have had numerous issues and Macpractice are stumped. When running in AUTO time selection settings on each computer, we think we have it narrowed down to the machines clocks in system preferences falling out of sync. I thought by setting times on each manually, and as closed to synced as possible that should solve it, but have found the server jumping ahead by 15 seconds in a weekend. This seems to corrupt server to client connection and there are certain functions we can't complete with our software. My IT guy hasn't seen this before, and I'm looking for more info. Any advice would be appreciated.
