I'd like to try and resolve this issue... Anyone know how to fix this? Thanks

    Hi

    On the server launch terminal and issue this command:

    sudo changeip -checkhostname

    Post the result. Hope this helps, Tony

    Thanks Antonio... here you go.

    Primary address = 10.31.3.135

    Current HostName = KNWS3135
    DNS HostName = KNWS3135.ad.ewsad.net

    To fix the hostname please run /usr/sbin/changeip for your system with the
    appropriate directory with the following values

    /usr/sbin/changeip <node> 10.31.3.135 10.31.3.135 KNWS3135 KNWS3135.ad.ewsad.net

    example:

    /usr/sbin/changeip /LDAPv3/127.0.0.1 10.31.3.135 10.31.3.135 KNWS3135 KNWS3135.ad.ewsad.net

    Hi

    Is the Server Standalone? If so run this command

    sudo changeip - 10.31.3.135 10.31.3.135 KNWS3135 KNWS3135.ad.ewsad.net

    enter the password when prompted and restart the server.

    If the Server is an Open Directory Master issue this command:

    sudo changeip /LDAP/127.0.0.1 10.31.3.135 10.31.3.135 KNWS3135 KNWS3135.ad.ewsad.net

    enter the password when prompted and restart the server.

    Before you do this can I ask if the DNS Service is being provided by an Active Directory Domain Controller? In other words a Windows Server. If it is and the Windows System Admin has created a DNS entry for your server then make sure there is a Reverse Pointer entry for your server. Make sure the Windows System Admin uses the KNWS3135.ad.esad.net as the FQDN (fully qualified domain name). Enter the AD Server’s IP address as the Primary IP Address in the DNS Server Field on your server and then issue this command:

    host KNWS3135.ad.ewsad.net

    You should see something like this:

    KNWS3135.ad.ewsad.net has address 10.31.3.135

    follow this with:

    host 10.31.3.135

    You should see something like this:

    135.3.31.10.in-addr.arpa domain name pointer KNWS3135.ad.ewsad.net.

    If you are seeing this after you have made sure the Windows System Admin has created the relevant PTR entry for your server then issue the changeip command again:

    sudo changeip -checkhostname

    This time it should report 'the names match there is nothing to change'

    Hope this helps, Tony

    Hi Tony, thanks for the reply...

    The DNS service must be coming from AD since the DNS service is not running on the server. This machine is bound to our AD network.

    I have no idea if a DNS entry has been entered for this server, how van I check?

    I'll wait to hear back before I run the command you suggested. Thanks!

    Hi Bruce

    Its always a good idea to let an AD Server know of other servers on the same network especially if you are planning to integrate and augment AD with OD.

    At some stage you must have asked the AD System Admin guy for an IP address - presumably the AD Server is also the DHCP Server? It would be at that stage that the request for a PTR entry should have been made.

    How does the AD System Admin guy do this? He/She creates the relevant entries in the forward lookup zone using the DNS Snap In module on the AD Server. Once he/she does that a PTR entry can be made for the NS and A records in the Reverse Lookup Zone.

    Hope this helps, Tony

    Hi Tony, I have already integrated this server into our AD. The machine was added to our AD via ADUG utility. We use static IPs here so this server will always be 10.31.3.135.

    I'm going to run your message by our ITOPS group and see if this is doable. Thanks
