problem with Windows Server 2003 built-in firewall

    I have a problem with Windows Server 2003 built-in firewall that manifests
    itself after a reboot of the server.
    At first I configured the firewall on a NIC to block all but web traffic (ie
    for a webserver) and also not block remote desktop.
    It worked just fine until I rebooted the machine.
    After rebooting, the firewall blocked all connections through that NIC even
    though the checkboxes indicated that it should not block them.
    Turning back off the firewall, the traffic was allowed through (of course)
    and the RDP and webserver traffic went through just fine.
    Flipping it back on, it still insisted on blocking the items that I selected
    to be unblocked.

    The NIC(s) in question (tried it on 3 servers on the same subnet) is the
    Intel 82551QM built into most Tyan motherboards.
    The other 2 onboard NICs are BroadCom BCM5704C.

    Has anyone else seen this problem?

  2. Hi Dave.

    I use Windows 2003 Server and have not seen that problem. The only thing I can
    suggest is to look in Event Viewer to see if there are any errors reported which may
    be related. Other than that double-check your configuration. In particular make sure
    that the ports are right for the exceptions and you might try changing the computer
    identification as in using actual assigned IP address instead of name or vice versa.
    of course IP address would only work well if computer had a static IP address or
    reservation in a DHCP scope. --- Steve
