why does \\server\share work and \\server.domain.tld\share not?

  1. Hi,

    As many we still use both netbios/wins and the dns name system. With some servers I have a strange

    What would be the cause for the failure of the "dir \\mailnew.tio.nl\c$\*.*" command when the
    similar command "dir \\mailnew\c$\*.*" using the netbios name does work?

    P:\>dir \\mailnew.tio.nl\c$\*.*
    Er is geen service gestart op het endpoint van het doelnetwerk op het externe systeem.
    .... Which translates to "There is no service started at the endpoint of the targetnetwork on the
    external system"

    P:\>dir \\mailnew\c$\*.*
    Het volume in station \\mailnew\c$ heeft geen naam.
    Het volumenummer is 6C74-B5F2

    Map van \\mailnew\c$

    As you can see both dns and netbios show the same ip-number for mailnew.
    The target mailnew is a Windows 2003 R2 server. There are some firewalls in between but they are all
    open for this path. The firewall on mailnew itself is not running.

    What would be the cause for the failure of the "dir \\mailnew.tio.nl\c$\*.*" command when the
    similar command "dir \\mailnew\c$\*.*" using the netbios name does work?

  2. In my domain both commands work and give identical results. I think you have
    a DNS problem.

  3. Hi Richard,
    I'd love to know I have a dns problem but.... what kind of dns problem would produce this result?
    What would I look for?
    All my dns zones are AD internal, all dns servers replicate.

    Another symptom that my be related is that when I am on my machine at home, which has a VPN to the
    company network and uses the same WINS and dns server as the mailnew sever, and I issue the command:
    net use \\mailnew\c$ /user:DOM\logonname
    it will reply within the 1 or 2 seconds asking my password but after providing that it will take 20+
    seconds to come back with the success report.
    After that a dir \\mailnew\c$ will produce the correct result straigh away.

    Doing the same for \\mailnew.tio.nl\c$ I have the same delay after providing my password but also
    after a success report I will have the another long 20+ sec delay when entering the dir command and
    before the results are produced.

    So something is probably wrong but what?
