    I have very recently been experiencing these errors when tryiny to do name lookups:


    # nslookup

    > 62.x.x.x
    nslookup: couldn't get address for '(L???K???
    ?': not found
    # nslookup

    > Default Server: ns0.domain.com
    nslookup: couldn't get address for '???????+'': not found
    #
    --------------------------------------------------------------------

    The above garbled response is from a FC4/ispconfig setup.

    Answers from a remote pc seem to suggest the name service on the FC4/ispconfig server is doing it's job:

    # nslookup

    > domain.com
    Server: 192.168.0.1
    Address: 192.168.0.1#53

    Non-authoritative answer:
    domain.com nameserver = ns1.domain.com.
    domain.com nameserver = ns0.domain.com.

    Authoritative answers can be found from:
    ns0.domain.com internet address = 213.x.x.x
    ns1.domain.com internet address = 213.x.x.x
    > set type=any
    > server ns0.domain.com
    Default server: ns0.domain.com
    Address: 213.x.x.x#53

    > 62.x.x.x
    Server: ns0.domain.com
    Address: 213.x.x.x#53

    Non-authoritative answer:
    Name: host.domain2.ltd.uk
    Address: 62.x.x.x

    Authoritative answers can be found from:
    domain2.ltd.uk nameserver = ns0.demon.co.uk.
    domain2.ltd.uk nameserver = ns1.demon.co.uk.
    domain.ltd.uk nameserver = ns2.demon.net.
    ns2.demon.net internet address = 209.246.126.109
    > 62.x.x.x
    Server: ns0.domain.com
    Address: 213.x.x.x#53

    Non-authoritative answer:
    x.x.x.62.in-addr.arpa name = host.domain2.ltd.uk.

    Authoritative answers can be found from:
    x.x.x.62.in-addr.arpa nameserver = ns0.demon.co.uk.
    x.x.x.62.in-addr.arpa nameserver = ns1.demon.co.uk.
    x.x.x.62.in-addr.arpa nameserver = ns2.demon.net.
    ns2.demon.net internet address = 209.246.126.109
    > 213.x.x.x
    Server: ns0.domain.com

    x.x.x.213.in-addr.arpa name = www.netexconsultants.com.

    HTML:
    [root@ns0 ~]# tail /etc/resolv.conf
    nameserver ns0.domain.com
    nameserver ns1.domain.com
    ; generated by /sbin/dhclient-script
    search domain.com
    domain domain.com
    [root@ns0 ~]#
    
    It looks okay to (the untrained eye) me

    You cant give dns name to a dns server, how shud the server know what ns0.domain.com have for ipadress if that hostname is the dns server? Do you know what i'm trying to explain?:)

    lerra is right. Put this into /etc/resolv.conf:
    Code:
    nameserver 145.253.2.75
    nameserver 193.174.32.18
    nameserver 194.25.0.60
    and remove
    Code:
    nameserver ns0.domain.com
    nameserver ns1.domain.com
