There is no good way to correct this situation. We recommend that NFS
volumes be kept separate from volumes used for AppleShare for this very
reason. The changes made by an NFS client are done behind the Finder's
back and require the folder be closed and reopened before the changes will
be reflected on the server and then the client. The problem is that there
are 3 different caches involved that store information on files and there
locations.
A workaround is to turn off the AppleShare Pro Folder Cache. With the
Folder cache off, the folders on the server and the clients will sync up
within 90 seconds. It is not necessary to do any window manipulation on
the server or the clients.
