Hi Team,

 

Unable to join vserver to AD and giving error as Unable to contact DNS

 

SA6CLS02::> vserver cifs create -vserver NS6VFL02 -cifs-server NS6VFL02 -domain wa6ads07.axabs-in.intraxa

In order to create an Active Directory machine account for the CIFS server, you must supply the name and password of a Windows account with sufficient privileges to add computers to the
"CN=Computers" container within the "WA6ADS07.AXABS-IN.INTRAXA" domain.

Enter the user name: aravind shastry.adm

Enter the password:

Hi,

 

Have you ensured the DNS service on the vserver is configured before attempting to join it to the domain? EG:

 

cluster1> services dns create -vserver vserver1 -domains testlab.local -name-servers 192.168.100.10 -state enabled -timeout 5 -attempts 3

 

cluster1> services dns show -vserver vserver1

               Vserver: vserver1
               Domains: testlab.local
          Name Servers: 192.168.100.10
    Enable/Disable DNS: enabled
        Timeout (secs): 5
      Maximum Attempts: 3

 

If the vservers DNS service is not configured\enabled then you won't be able to join it the domain

Hi,

 

Also i noticed you are attempting to create the vserver's computer object in the Computers container in AD (this is unlikely to be the cause of your issue) however the best practise is to specify which organizational unit the computer account is created in by using the -ou paramater. EG

 

cluster1> vserver cifs create ?
   [-vserver] <vserver name>           Vserver
   [-cifs-server] <NetBIOS>            CIFS Server NetBIOS Name
   [-domain] <TextNoCase>              Fully Qualified Domain Name
  [[-ou] <text>]                       Organizational Unit (default:
                                       CN=Computers)

 

This will enable you to delegate administration and apply group policy (as you can't apply group policy to a container object in AD). Also ensure that the Active Directory user account specified when joining the vserver to the domain has sufficent permissions on the OU to create the computer object and join it to the domain.The following table defines the permissions required to securely delegate Active Directory permissions to perform a CIFS setup and create computer objects for vservers within an Organizational Unit (http://support.microsoft.com/kb/932455)

 

  • Create Computer Objects
  • Delete Computer Objects
  • Reset Password
  • Read and write Account Restrictions
  • Validated write to DNS host name
  • Validated write to service principal name

Hope this information is useful

Thanks Matt.

I have tried with your options but no luck .

 

Data LIF is not able to ping Gateway and DNS server so i have raise a request to Network team to open firewall port open. Hope it will be work

What version of cDOT are you using?  We had a similar issue due to case sensativity and our Bluecat DNS system.  8.3.1 resolved the issue (see bug ID 886457).  Note that the workaround in this bug ID did not work for us and Support recommended the upgrade, which worked as promised.

Add ports to VLAN on network switch side  and do Vlan tagging at C mode
