Server 2008 R2 (64) SP-1 Event Error 5774 Netlogon

    Question

  • Hi there,

    I built another small network, single Dell 2950 as a Server 2008 R2 (64) SP-1 Domain Controller

    In the event Viewer is Event ID 5774 Netlogon error and desktops unable to connect, this is a new small developer’s network not in production, so I can make changes and reboot.

    The server name is Server01, “nslookup server01” comes back with :: as with IPv6

    This is a single DC and 4 desktops, no intenret or IPS involved.

    I have done the following which has not helped

    Added Reverse Lookup
    a. DNS
    b. Reverse Lookup Zones
    c. 1.10.10.in-addr.
    d. New Pointer
    e. 10.10.1.50, DC Name
    f. Test with NSLOOKUP from Server and Desktops
    g. Test with PING Server01
    h. Test with NSLOOKUP Server01


    IPv6 LoopBack On a Domain Controller
    a. Open the registry editor by typing regedit under Run
    b. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
    c. Right-click Lsa and click New. Choose to create a DWORD Value.
    d. Enter DisableLoopbackCheck as the name of the entry, then double-click to modify it.
    e. Set the Value to 1 and click OK


    DNS Updating IPv4 Adapters
    a. HKLM\Systems\CurrentControlSet\Services\Netlogon\Parameters
    b. Add the following DWORD value:
    c. Valuename = DnsUpdateOnAllAdapters.
    d. Value = 1.

    Disabled IPv6 in network adapter (unchecked)

    Under IPv4 default gateway is 127.0.0.1 (is that right?)

    Thanks

  • All is working, I did the following and all ping, nslookup, dns, dhcp, are working

    reg add hklm\system\currentcontrolset\services\tcpip6\parameters /v DisabledComponents /t REG_DWORD /d 255

  • I took a step back from this and undid this step, removing the Reverse Lookup

    Added Reverse Lookup
    a. DNS
    b. Reverse Lookup Zones
    c. 1.10.10.in-addr.
    d. New Pointer
    e. 10.10.1.50, DC Name
    f. Test with NSLOOKUP from Server and Desktops
    g. Test with PING Server01
    h. Test with NSLOOKUP Server01

    I also undid this step,

    IPv6 LoopBack On a Domain Controller
    a. Open the registry editor by typing regedit under Run
    b. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
    c. Right-click Lsa and click New. Choose to create a DWORD Value.
    d. Enter DisableLoopbackCheck as the name of the entry, then double-click to modify it.
    e. Set the Value to 1 and click OK

    I also undid this step:

    DNS Updating IPv4 Adapters
    a. HKLM\Systems\CurrentControlSet\Services\Netlogon\Parameters
    b. Add the following DWORD value:
    c. Valuename = DnsUpdateOnAllAdapters.
    d. Value = 1.

    New Steps:

    At the Adapter Setting for TCP/IPv4 The default gateway was set to 120.0.01, I changed this to the Server (Server01) IP address 10.10.1.50

    I also changed the ‘Perferred DNS server’ from 127.0.0.1 to the server (Server01) ip of 10.10.1.50

    Now,

    After this IP change, the desktops could see the DC (Server01 10.10.1.50) and under network on the server and desktops they see each other,

    Under DHCP, all 4 desktops have an IP from the DHCP scope I gave it - good

    Under DNS, all 4 desktops show up with their DHCP IP - good

    Problem,

    From the server I can ping the server by ip 10.10.1.50 and it comes back correct

    From the server I can ping the server by name ‘Server01’ and it comes back

    “reply from ::1”

    And ‘nslookup’ comes back with

    “Default Server Unknown”

    “Address 10.10"

    To creect this ::1 and nslookup "Server Unknown" do I need the reverse lookup put back and the 2 regedit changes put back?

    Thanks
