You were not connected because a duplicate name exists on network

Discussion in 'DNS Server' started by David Lazarus, Jun 14, 2005.

  1. Hi
    I have been requested to configure an alias for a server so that users can
    map a drive using the alias instead of the host name.

    I have a 2003 domain in native mode. On the dns server I configure a new
    CNAME record with the name of TESTR for a A record that already exists in
    DNS (the a record is "fileserver")

    When I go to a cmd prompt on a client machine, I can ping the TESTR name and
    it correctly resolves the fileserver ip address. If I ping the FQDN of TESTR
    it also correctly resolves the fileserver ip address.

    However if I try to connect to \\testr\sharename I get the message

    "\\testr\sharename
    You were not connected because a duplicate name exists on the network. Go to
    system in control panel to change the computer name and try again"

    I have tried using different CNAME values and regardless of what I choose I
    still get this error. Can anyone help.
    Thanks
    David

    You've already added a CNAME alias in DNS so that part's done.

    Now do this: Add the following value to the registry of the server:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
    Radix: Decimal > Value: 1 then reboot.

    Connecting to SMB Share on a Windows 2000-Based Server May Not Work with an
    Alias Name
