We have a Windows Server 2008 box hosting a very large file share on our LAN. We also have some Macs on our network that hit this share frequently. Sometimes though, when a Mac saves a file, and a user on another Mac, or another PC tries to access that file immediately afterwords, the file does not show up on the network share. Eventually the file does show up on the network share, usually after a period of minutes. This problem only occurs occasionally, but frequently enough to be annoying. Can anyone shed some light as to why/how this happens? All of our Macs run OS X Leopard, and they are all accessing the server via SMB.
