Windows 2008: Cannot access by computer_name

    My Windows 2008 Server cannot be accessed by name, but it can be accessed by
    IP. It cannot ping by name.
    Yes, the thing I checked it was the DNS, the DNS is clean, no event.
    Did the DCDiag, everything passed.
    The DNS Server is running.
    Where should I start to troubleshoot this problem?

    Update: I found some information in "Applications and Services", DNS Server.

    The DNS server is waiting for Active Directory Domain Services (AD DS) to
    signal that the initial synchronization of the directory has been completed.
    The DNS server service cannot start until the initial synchronization is
    complete because critical DNS data might not yet be replicated onto this
    domain controller. If events in the AD DS event log indicate that there is a
    problem with DNS name resolution, consider adding the IP address of another
    DNS server for this domain to the DNS server list in the Internet Protocol
    properties of this computer. This event will be logged every two minutes
    until AD DS has signaled that the initial synchronization has successfully
    completed.

  3. Hello Johnny,

    Is that the only server or are there more DNS servers? Please post an unedited
    ipconfig /all from it/them.

    IPv6 disabled.
    Firewall enabled on both (Server/Client), but I disabled and it did not make
    any difference.
    Yes, I have both under DNS Management Console, but only KOOL.COM has the
    servername and IP record.

    I see the problem, my DNS server from client side, shows 192.168.0.1.

  6. Hello Johnny,

    The problem is 192.168.0.1 the default gateway also is the DNS preferred.
    Your router is providing DNS? Then change it to the server.

    To get internet access for the domain, you have then to configure a FORWARDER
    under the DNS server properties in the DNS management console to your ISP's
    DNS server.

    Best regards

    No, My router is not providing the DNS. I don't see where in the router I can
    change it.
    I did put the router IP in the Forwarder under DNS, but it seems Win2008
    does not work this way, I had to put it in Default Gateway (server).

  8. Hello Johnny,

    Default Gateway . . . . . . . . . : 192.168.0.1
    DHCP Server . . . . . . . . . . . : 192.168.0.10
    DNS Servers . . . . . . . . . . . : 192.168.0.1

    Change that to:

    Default Gateway . . . . . . . . . : 192.168.0.1
    DHCP Server . . . . . . . . . . . : 192.168.0.10
    DNS Servers . . . . . . . . . . . : 192.168.0.10

    Difference on DNS is 1 and 10!!!

    I meant manually assign the DNS server IP on client PC, I did this before,
    but it till cannot access by name, only by IP.

    How do I fix this problem?

    Event ID 4013, Source: DNS-Server-Service

    The DNS server is waiting for Active Directory Domain Services (AD DS) to
    signal that the initial synchronization of the directory has been completed.
    The DNS server service cannot start until the initial synchronization is

    Meinolf,

    Is there a command I can type that will show me these two information?
    This way I can just copy and post it for you to take a look it.

    Please run the following nslookup commands and post the results:

    nslookup netserver
    nslookup netserver.kool.com

    If it doesn't respond, or it times out, there is another issue going on.
    Does the hostname 'netserver' exist in DNS as a host record under kool.com?
    If it doesn't, and this machine is a domain controller, than it appears
    there is something more going on with AD itself. You also posted you are
    seeing EventID 4013. That is indicative of a greater underlying error where
    DNS cannot see the zone in the AD database because AD has not initialized.
    As Meinolf requested, let us see your AD DNS domain name (as it appears in
    Active Directory Users and Computers).

  15. Hello Johnny,

    Open AD Users and computers, in the left pane you see your AD domain name
    at the top. For DNS open the DNS management console and use the forward lookup
    zone, there are 2 entries _msdsc.domain.com and domain.com or maybe more
    or less, please post them all.

    Best regards

    For AD name: KOOL.COM
    For DNS, under forward Lookup Zones:
    _msdcs.KOOl.COM
    KOOL.COM

    Under "_msdcs.KOOl.COM", I have one Host (A):
    NETSERVER Host(A) 192.168.0.10 static

    Under KOOL.COM
    I have the server its own, and the clients PCs.

  17. Read inline please.

    In
    There actually should not be a host record in the zone, _msdcs.kool.com. You
    should have in addition to an NS record and a SOA record:

    <VeryLongGUID> CNAME netserver.kool.com

    -and 4 sub domains-

    dc
    domains
    gc
    pdc

    If you are looking in the _msdcs(Gray) Sub domain, which is a Delegation, NS
    records for all servers, including itself, that have the full
    _msdcs.kool.com Forward lookup zone.

    Yes I have exactly what you have described (4 sub domains) + a very long name.
    I removed the A host record.
    and I still cannot ping by name, only by IP.

    Ping is not the correct tool for checking name resolution. Do all clients
    use the internal DNS server ONLY?
    Do they have the correct DNS Suffix search list? (Assuming you are pinging
    the host name only)
    Can you ping the fully qualified name?

    Does nslookup resolve the name?

    Yes, all the clients use internal DNS only.
    the nslookup cannot resolve the name.
