AD integrated DNS

Hi all,
I have a 2008 r2 server having AD installed. when i installed AD,DNS also installed automatically. so when i tried to add a client system as member it is showing error "
DNS server could not found". what shall i do now to solve this error ?

I agree with Susie. With any AD environment, all machines, which include the DC, member servers and workstations, must only use the DC for their DNS address and no other DNS addresses such as your ISP or something else on the internet, or AD will not function
properly, such as ou can't add clients, workstations will not register, etc.
Here's more info:

Active Directory Integrated DNS Zones, replicate only to specific domain controllers

I have a customer with a fairly large Active Directory forest with many domains that they are trying to consolidate into a single domain which likely take 18 to 24 months according to their timeline. During this time, they would like all DNS zones
to be serviced directly from the new domain controllers, meaning, domain A would have replicas of domain B, C, D, E, etc. Because the environment is complex and some domain controllers in domains other than A are in a very sad state and replication problems
abound, they would like to avoid replicating all zones forest wide.
I've never done this before, or even considered it necessary, is it even possible? I don't have a ton of time for trial and error, but based on this there seems to be some hope:
https://technet.microsoft.com/en-us/library/cc753801.aspx?f=255&MSPPError=-2147217396
Is this telling me how to do what I want to do?

He actually didn't specify much about dynamic updates requirements for old domains, if they don't need secure dynamic updates then a primary zone would work:
The DNS Server service allows dynamic update to be enabled or disabled on a per-zone basis at each server that is configured to load
either a standard primary or directory-integrated zone.

Integrated DNS role not installed

Hi all,
I installed an additional DC but the DNS role was not installed :
In the installation wizard, I selected the DNS server option in "Additional domain controller options".
After successfull installation and reboot, I had only 1 role active directory domain services.
Could you give hints where I should look at first.
Note : in the installation gui, it told me "there is currently 5 dns servers". I don't know yet where they are located. Also I have only 3 DCS in the domain (
nltest /dclist: )
thanks

Hi,
In addition to other’s suggestions, we can use nltest command or nslookup command tool to query all DNS server in AD forest.
For detailed information about how to use these command to query DNS list in a forest, the following link would be helpful:

OLD MX Records in AD integrated DNS

My DNS servers have old MX records referencing our old Exchange 2003 mail servers that are no longer present on our network.
Just want to confirm there is no issue deleting manually out of DNS. (I assume this is fine).
But also curious why the internel DNS would have MX records for Exchange 2003 servers...but Exchange 2010 servers have no mx records in DNS (our external name servers have the mx records).
Was this something with Exchange 2003? and changed in 2010?
Thanks

Hi,
Great advice from Vindum.
Exchange, like other email servers on the market, will first look for an MX record, then fail back to an A record. If the DNS server returns an authoritative result stating that there is no MX record, then it will look for an A record next. If an internal
MX record exists and/or it is incorrectly configured, your internal mail delivery may not work. More details about
Verifying DNS Design and Configuration, please refer to:
https://technet.microsoft.com/en-us/library/aa996996(v=exchg.65).aspx
By the way, please pay a attention to basic mail flow:
https://technet.microsoft.com/en-us/library/aa995988(v=exchg.65).aspx
Additional, I find a similar question about incorrect MX record, for your reference:

Unable to create DNS forwarder in my AD integrated DNS

Hi,
I have my mix AD servers (2003 + 2008) and im trying to create DNS forwarder to send requests to outside the Domain over natted IP for the name resolution. However, it works perfectly fine in my test environment.
Now, when i try to create on my production server, i get below error:
The operation requested is not permitted on the root DNS server
Please suggest.

Hi, it is worth checking if you have got a root (period) forward lookup zone. If you have, you will need to remove that before you can setup a forwarder. Hope this helps. If in doubt, please post some details of your forward lookup zones (with fake names).
Thank you

Externally Hosted DNS - How do I set up my 2003 DNS server for sub domain to point to internal IP address??

I have a domain name(domain.com) DNS hosted at my ISP. I also have 3 sub domains DNS hosted at the same ISP pointing to various external ip addresses (mail.domain.com, vpn.domain.com and ts.domain.com). We want to set up sales.domain.com to point to an
internal 10. IP address. We have AD integrated DNS servers for our 2003 AD domain. The AD domain name is totally different than the hosted domain name in question. I currently edit the host file for a couple of PC's but this isnt practical company wide so
I want to add entries on our internal AD DNS servers to resolve the locally hosted site. If i recall, someone once told me that you cannot just put an A record for one sub domain, I would have to have entries on my 2003 DNS server to resolve anything related
to the domain.com name. Is this accurate? If so, what is the proper way to configure my 2003 AD DNS server to resolve anything domain.com related for my internal users while still allowing my ISP to do the DNS lookup for the internet.

On my 2003 AD integrated DNS server...i rightclick forward lookup zone and choose...new zone..primary zone (store zone in AD checkbox checked)..i chose to all DNS servers in the AD domain for replication...zone name sales.domain.com....allow secure updates
option....then i added an A record in that zone...sales.domain.com..pointed that towards my internal 10. IP address...is this correct? It seems to be working correctly for the sales.domain.com DNS record...and i tested the other sub domains...and those look
like they are going to my ISP for DNS resolution...
Is this the correct procedure? I did this on a test AD domain and not my production...i want to make sure i dont break everything under the domain.com by incorrectly adding 1 sub domain..

Dynamic DNS (via DHCP) out of the box?

Greetings!
I was just wondering... Does OS X support Dynamic DNS updates out of the box?
I can't seem to find any confirmation if 10.5 uses bootpd (which I think it does), and if bootpd supports dynamic DNS updates with the named service built into Leopard Server. There don't seem to be any options in Server Admin to enable this... So I'm a little hazy as how to enable dynamic DNS without compiling my own version of ISC-DHCP.
Just for clarification here; what I'm looking for is the ability to update a DNS zone with a PTR/A record(s) of machines that send a hostname as a part of retrieving a IP address from a DDNS-enabled DHCP server. Ie, "mybox" requests IP from DHCP server, DHCP server updates "mydomain.tld" with a record for "mybox", so that "mybox.mydomain.tld" is resolvable afterwards by the machines on this subnet.
Cheers,
-SC

This is a strange topic because implementing Dynamic DNS on Mac OS X Server looks like it should be child's play... so why hasn't Apple done it? Could it simply be that Apple sees no need for it at this time? Mac OS X clients don't need it to sit happy with a Mac OS X Server. Neither do Windows clients using a Mac OS X Server PDC.
Apple has implemented Dynamic DNS client support into the Active Directory Plug-in in Leopard. In this environment, of course, the client's DNS server is most likely to be an Active Directory-integrated DNS server which happily support DDNS. Unfortunately this Dynamic DNS facility is not immediately available to those not using the Active Directory plug-in.

DNS/LDAP Issue for Trusted Domain

Hi
I'm trying to configure Configuration Manager 2012 R2 Forest Discovery to a trusted domain.
Objects from the trusted domain (users/computers) show up in the Collections, but when I check under Administration\Active Directory Forests I can see Discovery Status "Failed to connect using default account" and Publishing status "Cannot
Contact LDAP Server".
I've added the SCCM server to local admin at the trusted domain via GPO and have also created the system Management container.
When I check the log ADForestDisc.log I get this error message:
"Failed to connect to forest X. This can be because of disjoint DNS namespaces, network connectivity or server availibility issue. Error Information The specified forest does not exist or cannot be contacted."
I have setup Conditional Forwarders in DNS in both domains.
I have also read other forums about this issue and should have the answer:
"This error occurs for all of the domains that you mentioned and is typical when SRV records for DCs in those remote domains cannot be found. Forest discovery relies on DNS name resolution of SRV records to locate a suitable DC to communicate with."
"The site server performing the forest discovery must be able to resolve the SRV records for the DCs or root domain of the other forest."
We are using Windows AD integrated DNS in both domains.
I'm not so familiar with DNS configuration so I appreciate if someone could tell more specific how to fix this.
Thanks in advance

Hi
Thank you for your answer. This issue is solved. I've missed to open some ports in the router/firewall between the LANs.
The status under Active Directory Forests is Succeded now, but when I check under boundaries, I can only see the "Default-First-Site-Name" site for the first domain (same LAN as CM Server) and I can only see the IP address range for that LAN.
I don't Think this is a big issue, but shouldn't the site name and address range for the other LAN (where the trusted domain is) be automatically found to during forest Discovery when I've checked the options to create site and ip boundaries automatically?

How to use DNS server for name resolution for items which don't exist in active directory domain controller DNS

Dear Experts,
In our office we have a domain controller call it 'Office.com', all computers and corporate servers e.g. exchange, antivirus etc. are member of this 'office.com', it is also having a DNS. All users in office have there preferred DNS set to the corporate
DNS
We are working for ministry and offering services to them from our data center so have many servers which are for ministry but they are in our data center. For all these servers we created another DNS server which contains all entries for these servers in
forward and reverse lookup zones. In this DNS we also created a forward lookup zone for our corporate servers and zone name is 'office.com'
What we are trying to have is name resolution of all servers which are listed in other DNS build in our office on Win 2008 R2 for ministry servers
If the user change his preferred DNS to ministry DNS he can resolve the ministry server but then we can not control any thing through group policy since they are using other DNS and not the corporate DNS.
How this can be done ? like any group policy applied to corporate domain controller must take effect on users and in addition to this user must also be able to resolve server names in ministry project DNS
Please assist ASAP.
regards,

Hello,
ok so the GPO setting doesn't apply in any case.
Clients machines use the first DNS server in the list of configured ones on the NIC. If that one is available search for additional DNS servers will stop.
What i can not really understand is your description about the second DNS server. This should normally either another DC with AD integrated DNS, so everything is replicatedwithin AD replication or you use a secondary DNS on domain member server that pulls
the informations from the Master.
It sounds for me that you have configured a machine with DNS server role and created manually the zone with the same name as the domainand manually create there the required A records?

DNS disaster and how can stop it for future

Hi
Last week, I found lots of static records were deleted automatically from DNS server console which cuased lots of P1 in my environment.
I found some below envents before the time when issue occurred.
I want to know why DNS randomely Host reocrds were deleted automatically. Even opned case with MS but could not get anything from MS that why this was happened.
finally we resotred the DNS zones from backup tool and after restoring everythying was working fine.
please see some below events:

New Domain Controller DNS Issues

Hello,
We currently have 2 root Domain Controllers (ROOTDOM) and 4 child Domain Controllers (MYDOM). ROOTDOM is an empty domain, everything on our network uses the MYDOM domain.
These existing DCs were running Server 2003, so we upgraded the schema and added 2 Server 2008 DCs in ROOTDOM and 4 Server 2008 DCs in MYDOM. All servers are DNS servers and Global Catalog servers.
The AD replication status tool shows replication is working perfectly between the new and old DCs, and everything looks up to date in AD and DNS on all servers.
The new servers have a SYSVOL and NETLOGON share as they should.
The servers are all in the Domain Controllers AD group and have correct static IP addresses, forwarders are pointing to the 2 old 2003 ROOTDOM DCs which in turn point to an internet source which works fine.
The problem is that when I change the DNS server address of a machine in MYDOM to one of my new 2008 DCs, the machine appears to lose connectivity with the domain. As soon as I put the DNS server back to one of the existing 2003 DCs, connectivity resumes
as normal.
I really don't understand what else I'm missing on those 2008 DCs, could you give me any pointers of where to look?
ROOTDOM          MYDOM
2003RDC1         2003DC1
2003RDC2         2003DC2
2008RDC1         2003DC3
2008RDC2         2003DC4
                        2008DC1
                        2008DC2
                        2008DC3
                        2008DC4
The issue is slightly complicated by the fact that 2008DC2 has a hardware failure so DCDIAG (understandably) reports replication issues to that at the moment.
Any pointers greatly appreciated.

Hi Kev,
>>The problem is that when I change the DNS server address of a machine in MYDOM to one of my new 2008 DCs, the machine appears to lose connectivity with the domain.
Before going further, does the 2008 DC belong to MYDOM domain? For AD-integrated DNS servers and if these servers belong to the same domain, they should hold the same set
of DNS records.
Besides, we can check DNS event logs to see if some related events were logged.

Capitalization of DNS via Powershell? How to Change?

Yes - I understand DNS is case insensitive, but when working with a windows/linux environment we have an issue when doing zone transfers in linux.
host -l domain.com produces a variety of results that are have mixed capitalization. We're trying to determine how to rename DNS entries so that they are lowercase.
Is there any way to do it aside from removing a computer and rejoining it to the domain?

Not a scripting question. You need to ask in the DNS/Directory Services forum.
There is NO reason to change case on DNS. No web, Windows or Unix system pays attention to case. Unix will but only if you configure it to detect case in dns names. Windows cannot be configured to enforce case.
Unix and Windows web servers can be configured to enforce case in url strings but are not set to do this by default. I have not seen it done for more than ten years.
THe case of names in Indows AD integrated DNS comes from the system names. You would have to rename the systems to fix that. It cannot be done in DNS or in AD.
¯\_(ツ)_/¯

Dns backup

Dear All,
Somehow , We have collaborative delegated access on DNS along with client. Several time we see entry missing or modified.
We have window AD -DNS , Is there any way we can pull out DNS report on daily basis which includes everything in text file.
ZOne information , Host A record entry , Reverse , Everything...Kind of dump in text file.
Thanks in advance

It is best to have auditing in place for DNS to see what is going on. The link below gives you how to enable auditing for your DNS server.
Who Moved the DNS Cheese? Auditing for AD-Integrated DNS Zone and Record Deletions
For exporting part you can use dnscmd command and attach it to a schedule task which runs on daily basis. Refer to this:
Export DNS records to Excel to read time stamps and static records
But in a nutshell, this is the way of exporting using dnscmd:
dnscmd /enumrecords contoso.com @ /Type A /additional > c:\dnsdata\dns.csv

Exchange 2013 DNS for internal and external domain

Hi All,
I have been assigned a task to implement Microsoft Exchange Server 2013. I need some help in setting up DNS namespaces and design a strategy to have same internal and external names. Let me share some details here.
We have an Active Directory domain myinternaldomain.net, and we have a public domain
mypublicdomain.com and we have setup email policy to have
mypublicdomain.com as the SMTP domain for all the users. We have created another DNS zone in Active directory integrated DNS and created a records for
mail.mypublicdomain.com and autodiscover.mypublicdomain.com which will point to CAS NLB IP. We have 2 CAS servers and 2 MBX servers, we have configured DAG for MBX High availability and planning to implement WNLB for CAS as
hardware LB is out of scope due to budget constrains.
We want to have same URLs for OWA, Autodiscover, ECP and other services from internal network as well as from public network. Users should not be bothered to remember two URLs, using one from internal and other from public networks. I also want to confirm
that with this setup in place do i need to have myinternaldomain.net and server names in SAN certificate?
Thanks

Hi Sccmnb,
You can easily achieve this using split DNS.
Internal DNS hostname "mail.mypublicdomain.com" will be pointing to your internal CAS NLB IP and the external public DNS hostname"mail.mypublicdomain.com" will be pointing to the Network device or
Reverse proxy server IP.
Depending upon users access location(internal\external) the IPs would vary and they should be able to access the website with same name.
The names that you would require on the certificate(Use EAC or powershell to raise the request) for client connectivity would be
SN= mail.mypublicdomain.com
SAN= autodiscover.mypublicdomain.com
You don't need to have the active directory domain name present in the certificate.
Additional to this you need to update the AutodiscoverURI for all servers and OWA,ECP,Autodiscover Virtual Directories InternalURL and ExternalURL fields with appropiate public names.
Some additional Info:
*Internal vs. External Namespaces
Since the release of Exchange 2007, the recommendation is to deploy a split-brain DNS infrastructure for the Internet-based client namespaces. A split-brain DNS infrastructure enables different IP addresses to be returned for a given namespace
based on where the client resides – if the client is within the internal network, the IP address of the internal load balancer is returned; if the client is external, the IP address of the external gateway/firewall is returned.
This approach simplifies the end-user experience – users only have to know a single namespace (e.g., mail.contoso.com) to access their data, regardless of where they are connecting. A split-brain DNS infrastructure, also simplifies the configuration of Client
Access server virtual directories, as the InternalURL and ExternalURL values within the environment can be the same value.
