    Hi,

    On my Windows 2000 Domain, there appears to be no Domain Master Browser,
    even though in the registry on my Domain Controller the registry setting for
    the Master Browser parameter is set to 'True'. I know this because I am
    running the NetBIOS browsing console and it tells me this. - Any ideas?

  2. Identify the PDC emulator on your domain, usually the first DC
    assumes this role but it can be changed. Once doing this open
    a dos prompt and run nbtstat -n and verify a domain name 1b
    unique name is being registered by this paticular machine.
    Regardless of the registry setting the machine which registers
    the 1b name is the domain master browser.

    OK, so I have run the nbtstat -n command on my one and only domain
    controller and I get the following (amongst other things) :

    NETBIOSNAMEOFDOMAIN <1B> UNIQUE REGISTERED.

    I presume this is all ok then?

    HOWEVER, when I run netdom reset <computername>, I get an error saying RPC
    Server not available!!!!

  4. Make sure netbios is enabled on the PDC then open a dos prompt
    and attempt to map to a share on the PDC from the problem client
    first by tcp/ip address and then by name. If either fails what is the
    exact error message?

    Also if you are running WINS make sure the 1b name is in
    the list and pointing towards your PDC.

  5. You are attempting to use netdom on the PDC to reset the
    computer account for the PDC?

    OK

    On the only Domain Controller we have and, hence, the PDC emulator, I
    noticed that the following setting was applied :

    "Use NETBIOS setting from the DHCP Server"

    As this, obviously, had a static IP Address, it doesn't get anything from
    the DHCP Server, so I have enabled NETBIOS over TCP/IP.

    However, I still get the netdom error.

    Mapping drives in BOTH ways works.

    The 1b record points towards the correct IP Address. However, the record
    name is the Domain Name....Is this correct?

  9. Yes that is correct.

  10. I wouldn't think you have to worry about the PDCs
    machine account considering it is responsible for
    maintaining all machine accounts but I am not sure
    about this in W2k or higher.

    The Netdom error was actually fixed by disabling Norton Personal Firewall
    on the client. It obviously doesn't like port 135 being used!

  12. You've got to be kidding me? All this time you had a personal
    firewall running on the server? LOL That will definately prevent the
    machine from maintaining the browse list.

    No, not on the Server! On the client!

    I can now browse and see the Computer list using the NETBIOS Browsing
    Console.

    That is working but I still get errors now on my Domain Controller about the
    imaged PCs... Kerberos errors and "cannot find Domain Controller". To fix
    it, I have to add the machine to the Domain again and delete the DNS entry
    in the DNS table. When it reboots, all is ok.
