DNS Update Issue

I have no idea why I had this misconception. So I have been doing this incorrectly. Loopback addresses on all DC's. I just realized that there is no benefit to anything else.

@PhlipElder said in DNS Update Issue:
Why domain.com?
I didn't set it up. THis is how I acquired it.
Not worth the effort to change everything.
Exchange 2007 was also installed on a DC. /sigh

That's especially rough. I thought a file server was bad.

Simple case of me never doing this wrong I guess. What a weird thing to screw up. Didn't really have time to sift through it all.
What do you normally use for your top level domain on an AD build?
ad.domain.com theoretically. Everything I've ever touched is already in place. Although i'd love to rebuild my families infrastructure from the ground up.
If it looks like this, then it owns domain.com
Oh man, what a mess.
Meh, not bad actually. Perfect? No. But small enough to not be a problem really.
Definitely not what I would do now if I set it up new.
This is just a throw back to the new days of AD. MS suggested just this - then after a while they suggested domain.local for the internal domain, and now they recommend ad.domain.com for the internal domain.

Pretty sure domain.local wasn't the thing in Windows 2000 days, that came in 2003 and lasted, as you said, a long time.

I don't know about MS recommendation, but when I was setting up NT4 networks prior to 2000, it was the recommendation from the company on how to setup their stuff.

NT4, yes. But it behaved differently. AD I thought started with the .local recommendation.

man, after reading all this, I am pretty sure my DNS is not correct.

I'm just curious--what is it that we could prevent from occurring by putting DC2 first for DNS in DC1? In what scenario would we fail a lookup on ourself but succeed with a lookup? If replication is occurring they are the same. If replication is not occurring there is no guarantee that DC2 will have what you need vs. DC1.
Idk what I thought this for so long

This is just a throw back to the new days of AD. MS suggested just this - then after a while they suggested domain.local for the internal domain, and now they recommend ad.domain.com for the internal domain.
Being a part of the SBS crew from the BackOffice 4.0 and 4.5 (NT) days, the .Local phenomena started around the discussion of Internet domain registration and keeping the internal and internet domains separate. That was prior to SBS 2003 that was the first product to deploy out of the box with .Local.
Some had to do with the confusion around registering the internet domain that was to be used internally. We used to encounter companies with Domain.Com that did not own the internet domain. It was painful to say the least.
AD was still relatively new so no one really new what to do about internal and external DNS though SBS 2003 did split the DNS for Remote.Domain.Com.
Besides wizards, which were primarily in the SBS realm, splitting the DNS became the norm and eventually the recommendation came about for Corp.Domain.Com with the caveat that the internet domain should be owned.
So, here we are. Most companies own their internet domains so it's a no-brainer to split the DNS for their setups.
-
It really doesn't matter so much. Many places .com works great, many .local works great. Some, like mine, AD is .local but we also have onprem .com and public .com. Any issues? Not a single one, ever.
For the DNS server itself, it's own FQDN first, secondary DNS server(s) next, loopback last. For DNS or DHCP, you can have CF in there too.

@Donahue said in DNS Update Issue:
man, after reading all this, I am pretty sure my DNS is not correct.
I think I am with ya on this one.
So let me get this straight. On DC0 with AD Integrated DNS, Preferred DNS should be IP address of DC0 and Alternate DNS should be 127.0.0.1?
Currently I point DC0 Preferred to itself and Alternate to DC1. I have not had any issue over the last X amount of years so I don't know what the actual issue is with my current setup.
I currently have a .local also (setup by a contractor a long time ago).
-
@pmoncho No. The only entry should be 127.0.0.1. Always loopback.

There is no issue with your setup.
It's possible that the NIC itself could have an issue which would make your use of the actual IP fail connectivity, but the loopback would still function - but, I said there was an issue with the NIC, so does it matter if the loopback works when you can't get on the network?
As for having a secondary DNS entry - it protects you against the local DNS service itself failing, provides you a backup, just like secondary DNS to client machines have a backup DNS server to communicate with.
