  1. Hi,

    is it possible to share files on a network when all the computers are using APIPA and the device they are connected to is a hub/switch???

    File Sharing operates upon PORTS, not IP addresses Class A,C, or C.
    Windows Firewall however, *may* get in the way of your objective.

    With a decent firewall, you would create rules like:

    Allow in tcp/udp src range ports 137-139,445
    Allow out tcp/udp dest range ports 137-139,445

    Question: WHY? You mentioned hub/switch. If you do not have a router, then this
    setup suggestions you have a private lan without internet access.
    If you had a router, the DHCP service would be there and APIPA would be unnecessary.

    btw: the article sited above credits Microsoft for APIPA; not so. APIPA is provided by every NIC manufacture and is the default when DHCP can bot be found.
