Please Help me with DNS :(

Thanks for the response!

Computer name is just Server no .domain or anything
Server is bound to AD (could this be a Lion issue?)
* AD and Infoblox is integrated on the back end.

It is looking like this is a Lion AD issue because this all happened after we upgraded to Lion.

Are you setting the name using the changeip command from terminal? I know that apple has recommended in the past that is the best and safest way to set the local name to match the name that is listed in DNS. Also make sure that there is only one A Record in dns. I have seen in the past where multiple A Records can cause hovac to a mac server.

I don't have DNS running at all on the Server currently (nor on any of the other servers and they work). I did the changeip command and it says a DNS record error and the Infoblox guys say nothing is wrong on there end. Arg!

Just curious, what is the output of changeip –checkhostname?

Primary address = X.X.X.X

Current HostName = server.domain.com<http://server.domain.com>

The DNS hostname is not available, please repair DNS and re-run this tool.

Any way to have your DNS administrator manually insert / create an A Record in DNS for you?

They said they cannot. Infoblox seems to be crap.

Double check the DNS entries for your server using dig or nslookup, then

recently and it turned out to be a reverse lookup problem.

You mentioned in your original post that you were using lion and binding to AD. Im wondering if this may be a bug or something similar to the issues with lion client and binding to AD.

Hopefully someone else will chime in shortly and have an answer as I am now curious as well.

Host name would be something like: server1
DNS/FQDN would be something like: server1.example.com<http://server1.example.com>

Until you bind your server to AD, OD or whatever directory system you're using your server will be server1.local.

Only after your server is bound to a directory system will its name become server1.example.com<http://server1.example.com>. If your server appears to regress to server1.local then it's losing its binding. Verify that it is still bound in AD or that it's binding in the first place.

Don’t put server1.example.com<http://server1.example.com> in the Computer Name field if you're doing so. Put server1.

You also need to determine if your AD system is integrated with your Infoblox system. If not then you will need to manually create a DNS A record in Infoblox if that is what your organization is using for company-wide DNS.

A personal note and others are fine to disagree with me. I don't really mind occasional off-topic questions on a list for Casper. The expertise here is really excellent and diverse. But these types of questions would probably be better asked on the MacEnterprise list or a forum for the product you're discussing so that the signal to noise ratio is kept low here. I'm not a moderator and not trying to moderate; just a list member.

Sorry to be that guy again.

BUT my lion servers have successfully changed/updated it's hostname using the changeip command.

Bound to AD but no infoblox.

Regards,

Ben.

I've been in other environment where infoblox is used and experience odd DNS behavior. However, they've also been able to add/remove DNS entries. Have a hard time believing a DNS appliance does not allow manual entry, unless they don't have the necessary permissions.

We are a shared service environment. All I can do is ask.

We're in an infoblox environment and it seems to be fine. We have DynamicDNS enabled as well though so hosts register themselves with it and away you go.

Thats how we have things set up. We have another department that handles all of that (very silo'd and hard to talk to!). I wonder what is making things harder for us. The worst is when a Mac gets an address assigned with a stale record, the Mac just assumes that DNS name and all hell breaks lose.

Asking DNS folks to enable "scavenge stale records" is like pulling teeth. :(

We use scutil to force the Hostname in those environments, unless there's a compelling reason not to.
