    I do not know if this is the right forum for asking this question or not. I
    couldn't find a group for this server. If I have asked my question in error
    and someone could point me to the correct resource I'd appreciate it.

    I had this server working properly on my LAN for a long time. Over a year,
    maybe 2 years. I wanted to use VPN and needed to add another NIC card. I have
    a single 3COM 3c905B card and was adding another. First I just installed the
    card and started having troubles with the server seeing both cards at the
    same time. 3COM said to install older versions of the card first, then newer
    version last. So I uninstalled the cards in device manager, shut down, took
    the cards out and rebooted.

    I did the 3COM Pre-Install, shut down and installed the oldest version of
    the NIC card, rebooted, I was at the "Preparing Network Connections" screen
    for a long long time, then logged on to the desktop and now I cant get to
    Active Directory, DHCP or anything.

    I get errors in Active Directory that says the "Enterprise is not available"
    and "Workstation driver is not installed".

    I tried putting the original NIC card in and loading the software and I can
    access my LAN, (After using my router as DHCP) and the internet, etc. but I
    cannot install Active Directory, Uninstall it or nothing.

    I went into Add/Remove Windows components and removed all Networking
    Services except for TCPIP. I have ran dcpromo from the command line, but I
    can't uninstall Active Directory at all, it tells me it failed to find a
    suitable domain controller and when I tell it this server is the last domain
    controller on the domain it can't find the domain and wont uninstall.

    I don't know what to do at this point short of re-installing, which i hate
    to do. Maybe it's just something simple I am overlooking?

    Thanks for any help.

    You may want to start by checking your DNS and making sure that your cards
    are properly registered. Dual-homing machines means you have to watch for
    routing information to make sure it's appropriate. Obviously, you also have
    to be on the network and have a valid address etc.

    Thanks Al,

    I am back to one NIC card, the original and have access to the LAN and the
    Net (WAN) via a router I am now using as DCHP.

    DNS is supposed to be running on this server, but it is not. It's set up as
    automatic to run at startup. My server is identified in the DNS console,
    however it says it cannot contact the server. It was working fine before I
    didn the NIC change.

    For some reason it appears that somethings have gone back to a default of
    127.0.0.0 and "WORKGROUP" and I can seem to change anything or restart any
    services.

    I'm boggled.

    Thanks for the feedback.

    Let's start there then. If DNS won't start, you have a problem.
    What shows up in the event logs?
