Hi all, have weird problem suddenly. I was getting a DNS update error on client installs. My server has been installed with the setup-dns option. While trying to figure that problem out I dont know what I did but now the ipa dns server does not resolve any ipa clients. I had set it up as a forwarding server and it does forward requests (forward only) but now none of my clients hostnames can be resolved. Where do I start figuring this problem out.
A nood here so looking for all the help I can get
with regards,

Sameer, I am not the person to help you with this problem - but I can tell you that letting us know what Operating System you are using, and which version of ipa-server you are using, will always be appreciated!
Good luck

Also, start by demonstrating actual problems.
"none of my clients hostnames can be resolved" -> show how you resolve them with 'dig' utility. What is your /etc/resolv.conf on the machine where you run 'dig'. Explain which DNS resolvers are used there.
DNS resolution issues are typically due to: - having wrong DNS zone delegation or not having that at all - not talking to the right DNS servers - firewalls not being set up properly to pass DNS requests
my IPA server is linserver. IP: 192.168.0.111 domain is dcs.smcs
on my client machine /etc/resolv.conf namserver 192.168.0.111
when i dig linserver.dcs.smcs
I get no result. ANSWER 0
am on ipa server 4.5 on cent os 7
the firewall allows DNS requests. port 53, 80, 443 open for tcp and udp
thank you all for your time. any help will be appreciated

Sameer,
That ip address 192.168.0.111 is a private address, so I presume you are on an internal network.
The resolve.conf on the client has a spelling error - it should be
nameserver 192.168.0.111
Fix that and try again?
Note that CentOS will overwrite /etc/resolv.conf everytime you reboot. Google CentOS or RedHat resolv.conf to find a number of solutions to that issue.
Cheers L.
