Hello,  I suspect this issue is because of DNS request is not getting forwarded to next DNS. This issue is fixed in OneFS 8.x You can try creating forwarded in primary DNS and test it out it should work.  Thanks Chughh
Hi guys, i was wondering ifs someone came across the following issue and may have a suggestion  I have a 4 node X210 isilon cluster and i am trying to join it to two domains. i have configured 1 groupnet with 2 DNS servers and 2 search domains  ex. DNS  10.10.2.5                10.10.2.7      Search domain1.com                 domain2.com i have one subnet for each of these domains (10.10.2.100-10.10.2.108; 10.10.4.100-10.10.4.108) the isilon is added with the corresponding subnet service IP in both DNS servers  i have more issues which i came across trying to troubleshoot.  - when i try to add the isilon to either domain, i get a DC not found error - i can ping domain1.com in the situation above, but not domain2.com           - also i get the DC when running the _ldap._tcp.dc._msdcs.domain1.com command           - it fails with _ldap._tcp.dc._msdcs.domain2.com - if i invert the entries (both IPs and Search Domains) i can ping domain2.com and not domain1.com            - also i get the DC when running the _ldap._tcp.dc._msdcs.domain2.com command            - it fails with _ldap._tcp.dc._msdcs.domain1.com - all ports are open (i ran the nc -z DC_IP command)  Is it dependent to the way the DNS entries are listed? is there a best way to add the isilon to two diferent domains  what i wanted to achieve was the following: - isilon registered in both domains - three access zones (System, Domain1, Domain2) - System Access zones with local access - Domain1 and Domain2 access zones both with 1 AD authentication provider pointing to the same share so that users in both domains to access the shared resources.  I could really use your help because i am stuck with the troubleshooting and ran out of ideas. (tried also with two groupnets but this is not ok for me as i cannot have two access zones with the same base folder)  Many thanks! Mike.
