DNS Update Issue
-
The red box not masking, is the A record for domain.com
Everything here is subdomain.domain.com and has matching records on CloudFlare for when not in the office...
-
Are these Active Directory based domain controllers with AD integrated DNS set up?
Then DNS0 on all DCs should point to itself only. By default no other DNS server IP entry should be set on the NIC other than 127.0.0.1. Ever.
AD integrated DNS takes care of replicating changes and IDs among the DCs in a given forest/domain.
Never, ever, put a public DNS server anywhere but in the Forwarders location on an AD integrated DNS server.
DHCP should be handing out DNS entries for the AD DC DNS servers local to them or a tertiary if need-be for redundancy.
It sounds like whomever set things up had no idea how DNS works.

@PhlipElder totally.

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.

Okay, the masking threw me off.
_msdcs.domain.local
domain.com
domain.local
^^Zones?Why domain.com?
When we split DNS we usually leave domain.com to Internet DNS even if Location.Domain.Com is internal.
Then we set up the required internal DNS FLZs for services:
Remote.Domain.Com
SharePoint.Domain.Com
Mail.Domain.Com
LoB.Domain.ComApplication Request Routing (ARR) is used to parlay incoming HTTPS calls to their respective owners (RDS, Exchange, SharePoint, LoB) so we only require one WAN IP address with Internet DNS A records for the above pointing to the WAN IP address.
EDIT: To get around the AutoDiscover.Domain.Com we use the _autodiscover SRV record method.

loopback address on multiple domain controllers as primary? Contrary to everything I have read. Discussing with Jared right now.
-
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.

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.

MS originally suggested domain.local and stuck to it for a long time. That's how it started.

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 inherited a server 2003 that was set up like that.

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.
