    Default Trusted Zone IPs not accessible or disappear from Workgroup

    Hello,

    This is my first post on the ZA forum.

    We have a small LAN set up at home with a wired and wireless component. Each PC runs ZA and has a static IP which is declared in the ZA firewall (each PC has a mirror image of the trusted zone installed. By installing ZA on each PC we have effectively creating a second firewall against intrusion over and above that provided by our WRT54G Linksys router (attached to the DSL high speed modem as default gateway).

    Behind this we have a cascaded BEFSR41 defaulting as a high speed switch via the uplink port and connected to a port on the WRT54G.

    There are two Windows 2000 PCs and my machine running XP SP3. (The wireless is used by my son when he is home from university via his laptop).

    Recently, with probably the last two version updates of ZA, I have noticed that our work group lists fluctuate with one PC often not in the work group even though it is part of and defined in the work group.

    If I disable ZA on this particular PC and wait for the router table to update and the windows software to update the work group, eventually this PC will appear.

    If I re-launch ZA on the 'lost' PC after it reappears in the work group and then connect to any of the other PCs (or vice versa), the connections work fine. We can share printers, files etc.

    However, with each re-boot of the PCs or the LAN, this Windows 2000 PC often (but not always) disappears.

    Does anyone have any idea why this would happen and what I need to do to correct it?

    Please advise.

    Do you have DHCP turned off on all the machines and the routers?

    Hello,

    Thanks for your reply.

    DHCP is disabled on the 'gateway' front end router.

    The switch, by default has DHCP disabled.

    Hmm, not sure where to look next.

    Tryrebooting all the computers and routers at the same time. This "resets" all the IP addressing, and it may start working. Let me know what happens.

    Hello,

    Thanks again for the reply.

    I've done the re-boot re-cycle thing several times in the past few months with very limited success.

    I know that shutting ZA down fixes the problem on this one W2000 machine and that relaunching ZA after a successful connection from another machine works fine.

    Thinking about it further though, it may not be a W2000 or a ZA problem issue at all. I think if I access the work group from our other W2000 machine, the problem W2000 machine may appear without any intervention.

    If this does work it's got something to do with the XP and ZA combination that won't allow the XP machine to find the path to the work group computers.

    I can't confirm this though and will have to try it.

    Is your trusted zone security on medium?
