Clients randomly losing access to shared volumes
We've started experiencing a problem with our server, and I'm just wondering if someone here might have some ideas.
The Server is 10.4.8; it's more or less up-to-date, except for the last two security updates, which we'll apply as soon as possible (but I don't think our problem is related).
Our 10.4 clients (they're all either 10.4.7 or 10.4.8) are randomly losing access to one or more volumes shared by the server. They'll be logged in, and when they try to save a file to a network share, either get a message that they're no longer connected or they don't have permission to access the share point. Logout/login or a restart puts everything back to normal, but it's becoming a major irritant.
This is a dedicated file server; the only service running on it is AFP, and all files have permissions inherited from their parent folder.
