    I'll past a related thread below contains a related KB: The short
    observation is Appletalk seems to be more maintain more reliable connections
    when in mixed AFP 2.2 and AFP 3.x environments. Connecting via Appletalk
    while slower should take care of the problem of disconnects if no other
    resolution is found.

    Old thread below:

    Connections can be slept on a per connection basis - the Mac client may or
    may not be in use at the time a connection is slept and applications with
    files open on the shared volume may or may not generate the activity to keep
    the connection open. If the server is receiving traffic from the client in
    the required interval then the connections should not drop. This has been
    our observation using the network monitor tool in previous investigations
    and is why an afp incompatibility seems likely here. Using the network
    monitor tool on the server and looking at the time stamps of the traffic
    between the client and server during these drops can confirm.

    NT 4 servers only supported afp over Appletalk connections while the newer
    Windows server versions support afp over Appletalk and afp over TCP/IP. The
    Mac clients will prefer afp over TCP/IP if the server supports it.
    Appletalk itself generates enough network traffic when a share is mounted
    that the connections don't get timed out. If you are supporting Appletalk
    on your network then the clients should be able to force an Appletalk
    connection to the server by using 'afp:/at/server' instead of afp://server
    at the connect to server dialog. The connection type can be confirmed by
    checking the properties on the share.
