I'm trying to add a server (Server B) as a child domain to an existing forest.  The server was originally setup as a domain controller to replace the on prem domain controller, but was later decided to make is a child of the forest since the NAS on site can communicate with multiple domains of the same forest. I have removed the ADDS role and demoted the server. The old domain controller has a functional level of Windows Server 2012 R2 and the domain is called XYZ.com. This server was originally setup on a 192.168.60.0/24 network. IT Management has setup the new server (Server B) on a 10.10.16.0/22 network and want to make it a child so that it's domain would be abc.xyz.com. Management has also added a 10.10.16.x IP address on XYZ. On XYZ, I have setup a new site in AD Sites and Services with the 10 subnet and have renamed the original Site for clarity and have set it up with it's 192 subnet. Both servers are manually configured with IP/Subnet Mask/Default Gateway/DNS. Both servers have 2 IPs, one on the 10 network and one on the 192 network. From Server B, I can ping xyz.com by IP but not by name. When I try by name, the replys come from the hosted website. Each network has it's own default gateway. I then go to server B and add the AD DS role and then proceed to Promote the server. I choose the option to "Add a new domain to an existing forest". The "Select domain type" is set to Child Domain. I click on the Select button next to parent domain name where it asks me for …

We have a domain controller running Windows 2012 Server and it's also our DNS/DHCP server.  Non Windows devices acquire a DHCP lease, but fail to register in DNS.  Yesterday I added a non Windows device to the network, which immediately showed up in DHCP, but not in DNS.  This morning it finally did show up in DNS.  I added another device today and change the scavenge setting to 1 hour, but it still does not register with DNS.  I do have it checked to dynamically update DNS.

Maybe it tomorrow it will magically show up in DNS, but shouldn't it immediately be added to DNS when a DHCP lease is created?  How can I get this to happen without manually add it?

I know this is okay but I wanted to see if anyone could explain to me why our conditional forwarders do not resolve the "Server FQDN". I attached a screen shot. The conditional forwarders are on a domain that is setup on a trust relationship.

Everything else resolves and validates.

While running a network trace for a workstation slow login issue, I notice two lines for ldap queries which failed

1)  _ldap._tcp.<SiteName>._sites.<serverName>.<DomainName>   Response: Flags:  Response, Opcode - QUERY (Standard query), AA, RD, RA, Rcode - Name Error

2)  _ldap._tcp.<ServerName>.<DomainName>  Response:  Flags:  Response, Opcode - QUERY (Standard query), AA, RD, RA, Rcode - Name Error

I do understand how the workstation DC location services finds a local DC on startup.  But confused as to why both queries list a DC specifically and do not mention msdcs??

All DNS records are present and have run dcdiag and confirmed replication is running as well.

Thoughts?

We currently have our DAG setup with 2 exch 2013 servers. Right now if the dbs flips over to the passive node, we have our network guys make the switches on the routers so that it now points to the passive server instead of the one that was active, because there is only 1 outside IP address.
Now we are going to add another external IP address so that in the event the dbs ever fails over to the other server, we don't have to have the network team make any changes. They are going to set this up with the second external IP address..
My questions is, do I have to make any changes in the external dns for this to work or with the internal dns?

I have multiple Windows 2008 domain controllers and DC have DNS and DHCP role on it. I am planning to demote one domain controller (FSMO role in another server). It has DHCP and Integrated DNS installed. What steps I needs to take to remove DNS from this server other than dcpromo?

Hi All,

I have a quick question I hope you can help me to fix.

Environment: I have an environment where I have installed a new AD and the domain name is something like corp.example.com

As a NETBIOS name during the AD install wizard I did choose "example" to make things easier and consistent with the public DNS name. The public DNS registered is example.com and there is public website running with example.com already hosted by WordPress and DNS registrar is GoDayddy.

Issue: Internal host names are not resolved properly with NSLOOKUP

1. Hostnames are working fine

2. IP Addresses are working fine

3. FQDN are NOT working fine. They are resolved with internal domain appended to external domain name.

eg. "VM1.CORP.EXAMPLE.COM" returns VM1.CORP.EXAMPLE.COM.EXAMPLE.COM and public IP Address registered with the website DNS Provider

4. FQDN with a trailing "." are working fine

eg. "VM1.CORP.EXAMPLE.COM." returns the correct IP Address as expected

Configuration: AD/DNS server is pointing at itself. NO forwarders configured. AD is pointing at an internal Gateway. This gateway is configured to talk with the internet using a different network through a separate Router connected to the internet.

My question: It's obviously not a question of routing but I dont understand why DNS forwards queries for FQDN names to external DNS servers considering that "A" and respective "PTR" records are fully registered and working on the …

What is a quick but definite test to run from the Linux command line to check if dns requests are being hijacked. The test should not require having to change the dns servers for the device that the test is being run from.

Today we changed the DNS and MX records for my company's website and I am not sure how to confirm if we did it correctly since we are getting the Bluehost holding page. I know it can take up to 72 hours but I want to just make sure it is all in working order. However, when I run the website through intodns.com it gives me a lot of information I do not know what to do with.

The website is www.beechtreetrading.com

We bought the domain through G Suite/GoDaddy and Wix originally, and now are hoping to have the website on Wordpress as a mapped domain with Bluehost. We changed the DNS on GoDaddy to point to Bluehost and then since we have our business email set up through G Suite, we deleted the old MX Records on Wix and added the new ones.

Wordpress still says DNS configuration required and now when I try to preview the site in Wordpress it gives me this message: The webpage at https://beechtreetrading.com/?iframe=true&theme_preview=true&frame-nonce=82ddc6aeee&cachebust=0&calypso_token=c7539680-e97e-4b53-a62b-155823a59520 might be temporarily down or it may have moved permanently to a new web address.

Is everything still in the process of updating? Or is there a step we missed? Thank you in advance!

Hi,

I am migrating Ex2010 to Ex2016. They are running in co-existance mode right now.
This morning I changed the DNS settings to send my mail to the Ex2016 server.
Outlook and OWA are working fine, but users on phones/tablets are telling me that their devices keep asking for passwords and then don't accept them.
Any ideas?
Thanks,
Nacht

Anybody have info about hosted DNS and the Magic Quadrant? We're looking to host our public DNS.
